Bought one of these from Microsoft using the student deal which was a cracking offer (thanks to a friend at work). £359 but quidco gave £53 cashback and Microsoft refunded £30 as they forgot to include the windows store voucher (no great loss, nothing worth buying on there anyway!) so this tablet has cost me about £275! Originally I had an Asus T100 which was good, the quad core atom had plenty of poke, the 2gb ram never felt limiting and battery was excellent - 10 hours easily, The tablet section weighs about half that of the pro, and about the same with the keyboard attached. My first impressions were excellent. however it was buggy (bad WiFi drivers, volume control faults, required constant restarts) and didn't feel like it would withstand 18months hard use. I think if UK prices were more inline with US I might have forgiven some of its faults, but when the surface deal appeared I knew I had to change - my company is now a proud owner of a slightly dodgy t100. For those considering an Asus T100, its a nice little machine, but was released about 3 months too early. It probably isn't a fair comparison to a surface pro, but the Asus was £50 more although with the type 2 keyboard the surface pro has cost me about £50 more, but it is one of the nicest keyboards I've ever used. Had done lots of reading prior to purchase as I almost bought one at Christmas for £499, battery life is about 6 hours of average use which is what I expected. The only negative thing is it gets really hot under load. The T100 was barely warm when benchmarking, but the pro feels hot. The 80 degree ceiling is perhaps a little too high. I've downloaded a program called throttlestop after seeing on a forum someone mentioned you can alter voltages so will have a play later. I ran 3dmark 06 demo to compare with the Asus T100 scores. It scored an average of 2130, and the pro 5069. Both had gamebooster installed. Out of interest I installed the newer generic driver and score dropped to just under 5000, not large enough to be significant but perhaps indicative that the official driver is better optimised. Overall, a very happy pro user.
