I have the LG Optimus 7, and am extremely happy with it as a device. It has superhuman strenghth - past Nokia levels, the screen shows whites brilliantly, but most of all I love the physical buttons.
I don't need a flagship, I just need an option. Even if it has pretty poor physical buttons like the Lumia 710, I'd take it. I can wait a few months, after all Windows 8 and a new hybrid will be taking a lot out of my budget - but does anyone make smartphones with physical buttons anymore?
And if they do, will we see them running Windows Phone 8?
If Nokia ever decides to bring the 808 design to WP, the existing device already has a 3-button rocker identical in size and shape to the 710, albeit with different functions, so it wouldn't be a stretch.
Personally, I'm not a huge fan of physical buttons as they are just another mechanical part that can fail. I like the capacitive buttons that are currently used and even prefer onscreen buttons over physical ones.
I upgraded to a Samsung ativ s from my old trusty Optimus 7. It's a beauty of a phone, but it does bother me that the physical buttons are not there, except for home. I keep hitting the back arrow. You don't even have to touch it and it goes back. Drives me crazy. Also, not sure if it just me, but I feel like I could type better with the optimum 7 keyboard.
