Motorola CLIQ 2, or T-Mobile Sidekick 4G?

I am a teenager and have been looking up reviews and forums for both of these phones. I know they are different, and are kind of an odd comparison but I really like what I have seen about the both of them. I have never had a phone with android, and I really want one. The Motorola CLIQ 2 is cheaper, but it is also not 4G capable, I will not be doing any heavy duty work on it, but I will be using email, facebook, apps, youtube, etc., and I will have the 2 year contract, so I will have it for two years, and I didn't know if the Motorola CLIQ 2, since it is only 3G capable, would be extremely outdated by the time I have had it for a year or so. Which do you think I should get?
