iCloud.com on Surface 2/ RT?

Hi all,

I've been thinking recently about getting a Surface RT (or maybe Surface 2 if I can stretch to it) to complement my MBP, and to bring to uni to do work on.

I've just got a question though- how does it handle iCloud.com? (Specifically the iWorks apps on the site).

Please feel free to tell me if there's anything obvious I've missed.
