Sure, the webstore won't replace Crysis, Mass Effect or Dragon Age, but a casual 10-15 min of Angry Birds et al between heavy CLI sessions will do just nicely (no, I don't know what CLI stands for )

I have Jolicloud desktop (from webstore) set up as my home page; and I have to say I really like running Chrome now, it's like running ready-out-of-the-box linux distro on a virtual machine hosted by your browser - granted I run Chrome(ium) on Arch Linux already (on Windows 7 it's actually even more impressive). Installing apps is a breeze, exactly like on the actual Jolicloud OS, except you are running everything inside Chrome web browser.

Not sure if I could totally rely on cloud as my work puts me often in spotty WiFi coverage or mediocre 3G speeds for tethering. I'd hate to be on an overnight without being able to log on to my OS. I mean, no TMO for a day? Outrageous!
