i don't have the LX, but i did have the sidekick 3 and i did love it
it was a good phone but at the time i didn't have the best reception with t-mobile and so i left for verizon, but im thinking when my contract is over with verizon i will surely switch back, because a lot of my friends have the sidekick and they love it and are making me want it again lol..
it had a lot of neat features on it, but as a phone itself it was a good decent one
