(LJ told me my comment was too long, so here's the rest!)

I know this is a lot of info, but I hope it helps and doesn't confuse you. I am a gadget junkie, as I'm sure you've guessed, and most specifically a smartphone junkie. I will be happy to answer any and all questions you have, just let me know. But really your best bet is to visit a store and play with the phones yourself. The sales person will have their own preferences and from my experience tend to steer people primarily to Android or iPhone, but there are other options which are definitely worth investigating.
