I bought the Eve a couple of days ago. I'm a basic user, hoping to have the option of tweaking but not sure if I can do much if I can't root. Although, I enjoy having it, I experienced one main problem. After a while, the phone becomes sluggish...perhaps because all my apps are on internal memory. I did d/l an app that ends all active apps and that seemed to fix my problem. Perhaps a bug in 1.5?
I'm not sure if it's because this is a Rogers phone or not but it's quite slow booting up if turn off the phone...at least 2 mins for the homescreen to be useable.
As for the Eve receiving an Android 2.0 update? It's hard to say. From what I've read, it might not happen but if we all complained to Rogers about this, it might just happen...I'm trying to be optimistic
