Just got it this a.m. so haven't been through all aspects but so far I'm not impressed. Lot of conflicts w/existing apps, google calendar issues. Haven't seen much in a way of "speed" changes. Waiting to see how battery life changes. Don't see much sense in having all 7 screens on one page but maybe some do. My primary use of the Eris is for email/internet access/free texting and a few other things so I realize others may appreciate some of the new features.
