Way back before the iPad, there was the HTC Shift, a 7-inch UMPC with a 1024 x 600 touchscreen, a full QWERTY keyboard, EVDO data functionality and an 800MHz Intel A110 CPU. For mobility buffs, it was then what today’s tablets are to them now, but it cost an arm and a leg at $1,500. Even worse? It ran Windows. Vista. That alone was enough to drop the ‘f’ from the product’s name.
These days, you can probably pick up an HTC Shift pretty cheap on eBay, and while there’s still little to recommend it over an iPad (or, heck, even the Galaxy Tab) it turns out that the diminutive little UMPC is Hackintoshable, with OS X Leopard running pretty much flawlessly on it, with the exceptions of WiFi and the fingerprint reader.
If for whatever reason you’ve got a Shift around, or find yourself morbidly curious enough to pick one up cheap on eBay to make yourself one of the tiniest Hackintoshes around, you can find the instructions over on the XNA Developers forum.
