Apple released updates to its iMac line earlier in the week, bumping performance with the latest Sandy Bridge processors and AMD Radeon HD graphics cards. The new iMacs also sport ports -- one in the 21.5-inch models, two in the 27-inch -- for the new Thunderbolt high-speed peripheral connection interface that was introduced with the new MacBook Pros earlier in the year. Tested did a breakdown of the gaming capabilities of the new iMacs, determining that the best choice for many gamers will be to get the 21.5-inch model with a 6770M graphics card.

Apple also released the long-delayed, much-anticipated white iPhone 4 last month. If I may editorialise for a moment, the excitement over what is only a colour change is utterly ridiculous -- it almost makes me ashamed to be an Apple fan.

Arcade emulator MAME has a new project manager. After six years at the helm, Aaron Giles, a legend in the emulation scene, has stepped down to make way for Angelo Salese.

See here for the list. Head over to the SDL MAME website for a precompiled version, or grab the source straight from the MAME site.
