Well just be aware the OS is still a work in progress of sorts. Be ready for a glitch here and there. And just make sure you get one with good hardware.
There was a thread "to storm or not to storm"? just a few days ago that will probably answer your questions. I use the Pearl and Storm and listed my comparisons in that thread as did other posters. Hope this helps. Just use the search command for "Pearl" and "Storm"
