A review of the HTC Advantage X7501 mobile office device has been posted over at MobileTechReview.com. ‘For those who aren't familiar with the Advantage, it's a Windows Mobile device with a VGA display, triband HSDPA radio (that works on the US bands as well as Europe and Asia), GPS, 3 megapixel autofocus camera with flash, detachable full keyboard and of course it has WiFi, Bluetooth and other goodies. From the specs you might think this was a Pocket PC Phone (aka Windows Mobile Professional), but it's really designed as a handheld computer and notebook replacement. Yes, you can make phone calls but the phone radio is really there for data foremost. And yes, it's unlocked for use with any US carrier. The US retail price is $899.’
