This is an update of a deal I wrote about last year. Hopefully it won't sell out as quickly this time!

Looking to add a decent sound system to your laptop, or even an HDTV? When you're doing an end run around tiny, tinny built-in speakers, there's nowhere to go but up.

Every piano player or student knows how frustrating it can be to need a reference and not have it.

Offering a comprehensive directory of chords and scales, along with a reverse lookup tool, it is easier and faster than ever to find the perfect note. While installation is relatively painless and the interface is bare-bones (12 large icons in a grid), the layout … Read more

Annoying exes and telemarketers never seem to get the message when you're ignoring them. Instead of answering their call and telling them off, use Blacklist. It will hang up on any number you want or send it straight to voice mail. You can even modify it to only accept calls at a certain hour.

Backups are critical, period. Automatic or manual, full or partial, whatever -- as long as you're taking action to protect your irreplaceable personal files, your expensive software, and maybe your sanity. Full backups are best, but we also like extra protection for the data that changes the most, such as User files, as a backstop against those disasters that somehow seem to know when you're between backups. Everyday Auto Backup's name says it all: it makes automatic data backups every day (or when you want it to). It addresses some lingering issues about backup software, beginning with … Read more

We love simple games that require a bit of brain power to master. Cut the Rope Free is just such a game. And the fact that it's fun and appropriate for both adults and kids is a bonus.

We were impressed with all the different languages available with Cut the Rope Free: Spanish, French, Chinese, and more. It would be a great learning tool for kids young and old who are learning a new language. But besides that, it's just a fun game. The premise is to use your figure to slice ropes so that Om Nom, the … Read more
