I have the LG Envy2 through Verizon Wireless. I have had it for over a year now and am very happy with it. Having a fully "QWERTY" keyboard is great! There are a few awkward and annoying things. First, there is a lock system to avoid "butt dialing" which is great, but it can get annoying to have to disable every time you want to make a call. Second, there is a shortcut to Music on the front of the phone (which I personally never use, that's what my iPod is for) but if you want to access your contacts you have to dig through the menu for them. I have noticed that on the new Envy3 the music button has been changed to a contacts button. Third, when using the camera you have to open the phone to do so. Otherwise, you only get a small sliver of preview screen. It's also very annoying if you use the front screen to take a self portrait, you only have a sliver of preview to see what you are getting.
The Envy2 does have a really great speaker phone option when open. I can very easily hear the other person. It also accepts a SD Micro card for added photo, video and music storage. Another big perk is that is offers Bluetooth capabilities.
