I didn't have an Omnia and this was my first smartphone, so it may be a different approach.
The phone is really capable, but the current Android 1.5 is really a nuisance. If some people didn't notice it before, they definitely saw some things only after they upgraded to 2.1 (unofficially) with the leak.
If price isn't an issue, I would say wait for the Nexus One to come VZW, which seems to be soon. By the end of April, at the latest, since a rumored March 23rd date was released but then a report of a delay may have pushed it back a bit.
The N1 is the most powerful and capable Android phone you can buy, even when the Incredible comes to VZW. The Incredible will have the new Sense, but if you can live without a custom UI (like me) and use Home, you will enjoy the N1 the most. It has already been rooted (the Android version of the iPhone's jailbreak) whereas the Eris has not. The Droid has been rooted as well. Obviously the Incredible isn't out yet, but no one knows how long it will take to root that. If it's anything like the Eris, it will be a biznitch and may never happen.
But, if money is an issue or you just really like the Eris, it seems to be redeeming itself with this 2.1 leak making a lot of things smoother. I don't see any lag and it looks a lot cleaner and more crisp, but it still has a ways to go. Upgrading to 2.1 seems to be stable, but it does bring on a few small problems that you can read about in the Bugs and Fixed thread we have here, and decide if it's worth it for you. It seems as if the majority of the members of the Eris section (active members, at least) have taken the plunge and enjoy it. For some, the novelty has worn off, and a few are wishing they hadn't done it, but again, go through the 2.1 thread we have stickied and read responses. Ask questions if you have them, but only if they haven't been answered in the thread. You'll figure it out soon enough.
