1. I gotta admit... I don't like where the power button is. I usually hold the phone with my left hand while I use my right to swipe or press. The power button is right where I would normally hold on to the top of the phone. Its taking a conscience effort to change the way I hold it, so eventually it won't be a big deal.
2. I also agree about the homescreen. I use handcent, and if I am on the home screen when I recieve a popup, I can't turn the phone to landscape to use the bigger keyboard to post a quick reply. That is frustrating to me.
3. The button works fine for me. I kinda like it.
4. I don't care either way for a widget that lets you dial. I mean, hitting the phone button seems to work pretty well for me ( I haven't used an Iphone to know what you mean by this).
Overall, the speed is more then enough to make up for any shortcomings. The power button issue is one that has actually really bothered me. The oversaturation of colors, especially on apps like The Weather Channel has slightly bothered me. Other then that, I really like the dialer on the phone. As much as I liked wysie's contacts, the new dialer is freakin great. But I can't really complain. Its been a nice phone to have so far. Really nice. I just wish the Polar live wallpaper actually worked.
