Last summer I was shopping for a full Office license when
this popped up in my search results because it came with full Office. It was $350, but a $100 off coupon and some aging rewards the price was about the same as just the Office license, so I bit. I won't bore you with the specs (follow the link), but I like it a lot. All day battery, removable keyboard, and enough computer that Office is very usable. The keyboard is heavy enough to not require a kickstand and you can actually work off your lap since the keyboard is rigid. It's full Windows 8.1, so there is a DOS underneath for running legacy apps.
