i have an e61 and e62 and the e61 seems to be a bit snappier. if i hit menu on both at the same time the e61 will get to the menu first, but that could all be due to firmware or whatever is running in the background too. overall either one is great, i really like the wifi on the e61, and the pop port for stereo headphones. the e62 has a great built in im app, it just uses sms messages but whatever and blackberry works great. after using the e62 for a bit i really wish they had a "my own" key on the e61 it is really handy for getting to media app and the music player with just holding it down.
