If you erase and restore your iPhone, does performance improve?

I won't bore you with the gory details, but recently I had cause to erase my iPhone. And by "erase," I mean venture into the Reset menu and tap "Erase All Content and Settings."

Leading up to this, my iPhone 3G was running like a snail through molasses. In recent months it had grown weirdly sluggish. I'd pick up my daughter's iPod Touch and be shocked at how much faster it was.

After the nerve-racking process of wiping the 3G and letting iTunes restore the backup (it was the first time in a year of iPhone ownership that I'd had to do this), I noticed something: It seemed peppier. A lot peppier.

I'm not sure why, but this definitely begs the question: Should iPhone owners perform this step every few months? Does the wipe-restore process somehow defrag the device and thereby optimize performance?

I honestly don't know, but I reckon you, our brilliant readers, can offer some insight. Am I crazy? Imagining things? Or right on the money? (That'd be nice for a change.) Share your thoughts in the comments.

The Lightroom 3 beta will look familiar to current users, but there are changes under the hood. In addition, Lightroom catalogs can be synchronized with Flickr.

With the release of its first beta version of Photoshop Lightroom 3.0 on Wednesday night, Adobe Systems is trying to improve the heart of the photographic editing and cataloging software.

"With Lightroom 3, we're looking at a performance and image quality rearchitecture," said Product Manager Tom Hogarty. Those two goals are in opposition, since better image quality demands more computing horsepower. But Hogarty said the software is more responsive when moving among photos, and images look better with new noise reduction and sharpening abilities.

There are other changes, too, though: a revamped import process for importing photos into the software catalog; built-in connections to upload photos to online services and keep them in sync; a more flexible mechanism for laying out photos to be printed; new abilities for stamping watermarks onto photos; and the ability to export photos and music as a video file.

Along with a redesign of the iMac, MacBook, and Mac Mini, Apple today also unveiled its new Magic Mouse, a departure from the underwhelming Mighty Mouse Wireless that flew beneath the consumer radar back in 2006. The new Magic Mouse is also the next device (after the iPod, iPod touch, and MacBook Pro) in line to receive a dose of multitouch capability.

Check out various Apple Magic Mouse gestures.

We've only had a day to play around with the multitouch features, but so far we're still on the fence about switching from our Logitech Performance Mouse MX. There's certainly no denying the aesthetic appeal: the bottom half is sleek aluminum and the top shell is made of a milky white shade of polycarbonate with a subtle gloss. The entire surface is a single button (no Mighty nipple, of course), but you can also change the settings to recognize a right-click or a lefty orientation, as well.

The multitouch user area is spread across the entire surface of the mouse, so you can swipe your finger anywhere and expect uniform results. Aside from the two main buttons, you can also scroll 360 degrees around a Web page, photo viewer, or document using a single finger, or quickly navigate forward and backward in a Web browser by simply swiping two fingers horizontally across the top of the mouse. The last feature is basic, but useful: holding down the Control key on the keyboard while scrolling up and down with a finger lets you zoom in and out of virtually anything onscreen.

Like the Mighty Mouse, the magical sibling connects to your computer through a simple Bluetooth pairing, and it works with any Mac running OS X version 10.5.8 or later, as long as it has the latest Wireless Mouse Software update 1.0. Windows users will bemoan its inability to work with non-Mac PCs.

Today's guest on The 404 Podcast is The Paper Raincoat, a local band of the "experimental rock ambition" genre, as Jeff calls it. Amber Rubarth and Alex Wong have both garnered musical recognition for their individual acts, but only recently came together to form The Paper Raincoat. The release of their first EP, Safe in the Sound, ushered in an international fan following and an impressive list of accomplishments, including the iTunes Indie Artist Spotlight. We're very excited to have them in the studio with us today, and they come bearing instruments for a live acoustic show!

As we talk to more bands, we're starting to understand the long process of dreaming, writing, playing, and touring with your music in the current music business scene. With outlets like Facebook, Myspace, Last.FM, and many more, artists can easily cast a wide net over an audience that would normally require a major label contract to reach. We talk with The Paper Raincoat about the naming of the band, their recording process, their fantastic DIY album art, and their upcoming tour.

In case you haven't figured it out by now, there are a million places to stream their music live, but the best thing you can do to show your support is to preorder a CD. One-hundred percent of the preorder money will go to printing the record, and you can pick between three packages, the highest of which lands you a limited edition CD, two signed posters, a T-shirt, and a custom USB wristband drive with a personalized video "thank you" and exclusive video content from the band. In the meantime, you can also follow the band on Twitter, attend their CD release party at Joe's Pub in NYC, and download their brand new song, "Right Angles."

The HT-RC180, the best-sounding receiver for a grand.

Powerful-sounding receivers are hard to come by.

Sure, you can buy respectable-sounding models from the usual suspects--Denon, Marantz, Onkyo, Pioneer, Sony, and Yamaha--but most of the more affordable models lack real muscle. They sound acceptable at moderate volume levels, but can't fully convey home theater impact the way bigger, read "more expensive," models do.

Onkyo's new HT-RC180 ($1,049 MSRP) is THX Select2 Plus Certified and that's always a good sign. A bevy of features including an Ethernet port that enables the HT-RC180 either to receive and output audio tracks playing on your PC, or to bypass your PC and directly stream Internet radio stations such as Rhapsody and Pandora. There's five HDMI 1.3a inputs and the ability to upscale any video input to 1080p via Faroudja DCDi Cinema. You'll soon get the complete scoop in the full HT-RC180 review I did with Matthew Moskovciak.

The features are nice, but it was the HT-RC180's power and dynamic slam that wowed me.

The very first thing I noticed about the HT-RC180 was its ability to play nice and loud without strain. True, in absolute terms it probably can't play much louder than lesser receivers, but the HT-RC180 definitely sounds better playing loud. Home theater, at its best, is all about producing a more visceral experience, and the HT-RC180 does just that.

Earlier this month, I encountered an Adobe Photoshop Lightroom analysis by consultant Lloyd Chambers that expressed surprise with a facet of the image editing and cataloging software: it didn't export photos as fast as possible.

Chambers found that if a photographer wants to produce JPEG or TIF images from the originals in the program, the fastest way is to divide the batch into thirds and export each third separately. Using a modern Mac Pro system, exporting a test set of photos took 351 seconds as one batch and 189 seconds divided into three batches running at the same time.

"The big disappointment is the sluggish performance importing and exporting files, which are tasks that are key to efficient workflow--tasks one has to do over and over. Most of the 'juice' of a Mac Pro goes untapped," Chambers concluded. "You have to load it up with more than one job to force more of the available CPU cores to be used. Lightroom should do this automatically!"

The study caught the attention of others, including Scott Kelby, head of the National Association of Photoshop Professionals. I was intrigued, too, because although many programming chores are difficult to spread across multiple processor cores, exporting photos is trivially easy since it breaks conveniently into independent bite-sized pieces. So I thought I'd see what Adobe had to say for itself.

I recently participated in a Podcast focusing on subwoofer performance with Home Entertainment magazine's Editor-in-Chief Geoff Morrison, Director of (loudspeaker company) Revel Products, Kevin Voecks, and Brent Butterworth, a freelance writer for a number of magazines including Sound & Vision.

Voecks immediately zeroed in on the importance of placement, which is absolutely crucial to getting the best out of any sub. I'd go so far as to say an average sub, perfectly placed and set up, will outperform a great sub that's been carelessly placed and set up. That's because the sub's interaction with room acoustics can play havoc with sound, all too frequently resulting in boomy, uneven bass.
