I would for sure. It's the best phone on Verizon right now in my opinion and because they have the best service and I hate the iPhone because it cannot multitask I would never switch. I love the Sense interface and until the Desire or Incredible comes out for Verizon it will continue to be the best phone on Verizon. I came from a Touch Pro 2 which I really liked but Android is far superior to WinMo.

This is, for a lot of reasons, the best phone available on the best network possible (Verizon).
Without taking consideration into rooting + overclocking + optimizing (which all voids your warranty, technically, anyway), the Droid is in many instances SLOWER than the Eris.
Why? It has 400,000+ pixels to push on every screen, when the Eris has ~154,000. Even with a dedicated GPU and faster processor, it's a slower device in many respects.
Home on Eris is FASTER than Home on Droid.
Other than not having a camera flash, and CONSIDERING the imminent upgrade to 2.1, I would definitely buy Eris again.
I just got one of my friends to buy it (right now Verizon's running a smart phone promotion - as long as you've been with them for 6 months+, and the smartphone is an Upgrade for your plan, you get it at the New Every 2 price, even if you JUST got a phone) and he couldn't be happier, even knowing that new phones are coming very soon.
That being said, even if you like root, there's a good chance that the newer HTC phones, like the Incredible, for Verizon, will NOT be rootable. The Eris was locked up incredibly tight. We got lucky and a ROM got leaked. For me, because I have it rooted, I'm already sold on it. Would an N1 be better? I would say no, without SenseUI, even though it's faster.
The point?
For me, SenseUI + form factor (physical call/end buttons) + better touchscreen than droid (or non-HTC phones) + rootability (for me anyway) + being a great phone on its own (IMO) = YES on the Eris.
I'd like the N1 better when it comes out, if it had SenseUI and physical call/end buttons, and the Incredible better if it were Rootable.
For me: Eris is #1. Even though the processor is 3 years old. Speed is a convenience. Sometimes it's not there. Functionality is all I care about.
