Brand new here. Decided to do some research on the 650 before I plunged. I see how great it is now thanks to this site. I've long outgrown the sidekick 2 and the 650 will much better suit me. Mp3 player, can view excel files, better email client, better web browser, can use as a modem for my laptop. The guy has the 650..had a sidekick before that..and now wants a sidekick again. Beats me

but I'm not going to argue. Getting his 650 and bluetooth stuff for my sidekick2 with extra colored sides and an extra $125 because it's in bad shape but functioning. I think it's a steal. Going to make the deal tmrw night.
Any problems transferring to the treo? I'm thinking I just stick my simcard in, since it's unlocked, and then i contact Tmo about it and tell them i want to cancel the sidekick plan and get the unlimited data plan and keep my same talk plan.
For the mp3 player..i realize that the phone uses a bluetooth headset, but is there a hole on the phone itself for a set of stereo headphones like u'd use on an ipod?
Also, does the 650 have the ability to view adobe acrobat files..pdf files? and how about powerpoint documents? I'm a biology student and a lot of the files I use are in that format.
Thanks for the help. I'm looking foward to my new phone and ditching the sidekick.
