I have a maxxed out XPS 13 and its a love-hate relationship. The screen and build quality is great, the keyboard ok and the touchpad as well. There's very little to match it in that form factor right now

It's noisy as hell though, I can't say that battery life is great and I have some weird problems with music stuttering when I compile, also Visual Studio ocassionally locks up on deploy for some reason.

If I could have a Zenbook with the same screen thought I'd take that any day.
