I'd definitely search around for comparisons because there are a lot of them. Most people agree that it isn't worth the upgrade if you already have the Esteem. They are both excellent phones. I think it comes down to what you use your phone for, but due to the cost you may be better off keeping the Esteem for now and wait for an even better phone to come along. The Connect is dual core and has a bit better screen, but no HDMI and some people really aren't happy with the .3 inch size decrease. It does give you the ability to talk and access the web at the same time though. Also most apps don't utilize dual core yet and this phone may or may not get ICS. If you are really this unsure, I'd stick with the phone you have and save the cash for later.
