Samsung Behold vs Samsung Memoir vs Samsung Highlight?

These phones seem like the best phones I can get on T-Mobile without a data plan. The main reason I am getting a phone is to text, browse the internet, use as an mp3 player (I have a 15GB music library) and to take quick but not necessarily quality pictures (as I already have a point and shoot and a DSLR) I need a phone that will fit well into my pocket (I wear skinny jeans) and to be durable but also stylish, meaning I don't want a brightly colored kids phone encased in rubber. I will be using this phone a lot during the day to check Facebook, text, but won't be using it much for calls.
I've been researching these phones for several weeks now online but haven't had the chance to actually hold one and try it out yet. Please give me any suggestions you have, right now the Behold is my primary choice but if anyone has checked out either of the other phones if you could give me a run down of the pros and cons compared to the behold, that would be fantastic.
Thanks in advance!

my knowledge of these phones arent that great but id have to say memoir
and honestly speaking, the highlight looks ugly

highlight, entry level everyday touch, looks cheap, costs more than a a behold on contract
behold, the veteran of the group, semi high end, better than the highlight, quality rig, cheaper to buy on contract
memoir, high end, real point and shoot camera, not too expensive considering the camera, behold on roids

no the behold and memoir dont have threaded texts
atleats the behold doesnt
i knoe it sux
but if you're looking at t-mo touchscreens
then also look at the G1 and Mytouch
the MyTouch is supposed to be a great phone

lol
i bet it will
lol

i think so, but the big diff is it comes with this app that will ajust to ur fav places to eat, movie place, store, locations, contacts, site, etc
