Business laptops

We have a new starter at work who requires a Windows laptop. We don't want to spend too much ( below£600), but would like to get him a reasonable Win8 laptop. He'll spend quite a bit of time on the road, so an ultrabook would be perfect. I've looked at dell, and acer so far. The acer S7 looks tidy but a bit too expensive for the budget. Any suggestions please? I know I can trust the opinions on here.
