I can get a new laptop via work - £800 (ex VAT). I'm after an ultrabook for portability and being reasonably quick would be helpful. I think an SSD is essential because work encrypt our drives and it slows stuff down a bit.

Any advice? I really like the Lenovo Yogas but think I can only really stretch to a Yoga 2 Pro. The new Yoga 3 Pro is probably too much. Any others I should look at?
