Even ignoring the inanity of comparing a PC and mobile game... DDO is supposed to be impressive? Really?
Only true if you're buying shitty phones. The primary use for my phone is business email, then browsing, reading/editing docs, the occasional SSH and time killing stuff like games (the one above, Worms) and Youtube. You seem to have some weird idea that everything needs to fall into either PC-level performance/ability or only be able to make calls. I have to say, that's a silly and false dichotomy. Modern smart phones are getting good enough to replace UMPCs/netbooks in most circumstances. The only time I even pull my netbook out anymore is when I need to console (serial connection) into a device or cap packets, or type up a long email. Nearly everything else I'd use a notebook for on a day to day basis is covered quote well by my phone.
