Personally I came from the Optimus v, so I had a great working phone. But I was bored with the "tiny" screen and relatively slow processor (I say relatively because it ran really great compared to other androids my friends had, and waaay faster than a friends Optimus S).
I debated with myself before it came out, and ended up buying one the second week once I actually found one.
I don't regret it at ALL. I haven't had the radio error nearly as much as some people in the forums, and a quick airplane mode normally fixed it for me. But with the new(newest) radio flashed I haven't had any errors.
Unlocking the bootloader was pretty easy, and I held off on doing soff for quite a while. Actually it was about the time Leslie Anne posted the turn your evo v into an evo3d thread. And to be honest it was a lot easier and less scary than I thought. It took me about 15 minutes of tapping the wire, and after I remembered reading to press the wire TWICE when it tells you, I was soff'd!
I say if you can get a great sale on this phone dive in, I wouldn't pay full price this late in the game. There is bound to be another awesome phone around the corner.
Sorry I rambled too much caffeine.
I'm just too scared to attempt all of that stuff just to get the radio to function normally.
