So, I rounded up a G1 off of craigslist for $100. I was really hesitant to give up a hardware keyboard (I had a BB curve 8330). Like said before, this phone will be similarly spec'ed. It should not be too bad (the Zio has more ram than the G1) but I would venture to say there will be hardly any 3rd party efforts and therefor no 2.1 and i'm not sure i'd be willing to pay $300+tax. The G1/myTouch3G border on being laggy, I couldn't imagine this phone being much better than those.
