Well, it really depends on what you need. The Sidekick is better for browsing the web and sending/receiving SMS's and emails but is a harder phone to use. On the other hand, the W600i supports nice gaming and music playback with better RF (and 850Mhz in case you head to a rural area) but has a poor keypad. Both have a crappy camera but the Hiptopss is crappierer. Personally, I would love to have a Hiptop2 but to make the right decision you have to decide what you want for sure, thats the first step.
