An anonymous reader writes "The community at www.MicroPCTalk.com have spent the last few years devising all sorts of mods and tweaks for the Sony VAIO UX-series UMPC. Now they've thrown nearly all of their major breakthroughs into one machine. Using the latest UX model (UX490) as the base, the original SSD has been swapped for a speedy 128GB SSD, the CPU has been unsoldered from the mobo and replaced with a Core 2 Duo U7700 (making this probably the smallest computer to use said CPU). The original EDGE module has been removed, and carefully put in its place is an E169 Huawei terminal which provides up to 7.2mbps 3G (HSDPA), voice and texting. On top of this, the unit quad-boots Mac OS X, Windows 7, Windows Vista, and Windows XP (and the Huawei terminal works under Mac OS X as well)."
