the sidekick is much more social friendly so if you like myspace facebook and other internet sites its great. it is also good if you like games and stuff because they can be downloaded through the download catalog. it has a great screen and nice camera. however, the blackberry is nice too...the suretype takes a little while to get use to but once you do its a texting machine...ive had both and honestly i would buy the sidekick ne day over a blackberry
