A Micro PC Talk member named "anh" has radically modded a Sony UX490 UMPC to run four operating systems, including Windows 7/Vista/XP and Mac OS X Leopard 10.5.7.
"Instead of a 1.2GHz Core 2 Solo U2200 and 48GB SSD, the uber-UX490 has a 1.33GHz Core 2 Duo U7700 – overclocked to 1.438GHz – and a speedy RunCore Pro IV 128GB SSD," wrote SlashGear's Chris Davies.
??"A voice-capable HSPA modem has been squeezed inside, together with a/b/g/n WiFi. Not a mod process for the faint of heart, but an example of how far enthusiasts will go when the company themselves give up on a platform."
??"anh" explained that he had begun the extensive mod by reducing the unit's heatsink.
"To fit [the] E169 perfectly, I cut a piece of heatsink to create a space for it. Then I also have to trim E169, remove [the] antenna. [The] unused cable is USB, but VCC is only 3.3v so I get another 5v source to feed E169. USB Data is used from unused cable which taped on SSD/HDD [and the] built-in USB port is free to use."
