So its time to upgrade. This will be my first smart phone. I want to be able to use it mainly for internet, but also GPS, and tethering. How much better is the Slide verse the old MyTouch 3G. The mytouch is only 50 bucks right now, and thats a great deal on a smartphone. I really want to hear some feedback on these phones, and why or if the Slide would be worth that extra money.
