I have a Dell Latitude E7240 (12.5" Ultrabook) that, while not as svelte as the new XPS 13, does the job when I need a more powerful laptop... which is exceedingly rare seeing as it's been docked on the desk in my home office for the last 10-months and is really only used the first Monday of the month when I need to use VPN to run month-end reports. Also, with the original T100TA and Surface Pro, I very rarely use the touchscreen when the keyboard was attached (pretty much only for the charms menus) and only really used it when using as a tablet.
