Ultrabooks from Toshiba, Acer, and Samsung remain at relatively low prices at major retailers like Best Buy compared to analogous offerings from Apple.

Prices for the 13-inch Toshiba Portege (Z835-P330) and 13-inch Acer Aspire S3 (S3-951-6646) have stayed at $799 for many weeks since they were announced last fall. Currently, both are listed at Best Buy for $799.99.

There was a time when IBM's mainframes were cutting-edge machines for scientific and engineering calculations.

Those days began in the 1960s, when IBM's System 360 rewrote the rules of computing and before humans walked on the moon. Big Blue long since has moved its high-performance technical computing effort toward its high-end Blue Gene systems and more conventional Linux servers using Intel and AMD x86 chips and Unix servers with its own Power processor. IBM's System Z mainframe line is now geared for commercial customers who are willing to pay a premium for reliability and high performance for … Read more

I've got 99 problems but a glitch ain't one.

Right now, that's more than Apple can say. The company is trying to fix a glitch that has resulted in iTunes Match filtering out explicit lyrics from what appears to be a small number of rap songs, according to the blog Cult of Mac.
