I need expert advice. Starting this fall, I will be commuting once or twice a week to grad school. The trip will likely take about 100-120 minutes each way (40 minutes on the New York City subway, 40 minutes on the commuter rail, 20 minutes walking, 10 minutes waiting). I think I should get some kind of mobile device so that I can be productive on the train. (Before we proceed, I want to make clear that I don't want to hear any judgmental "Read a book" cracks from anybody. Sorry, I got a bit ticked after reading that on a Yahoo feedback page.) I don't think a Macbook is a good idea (the commuter rail ride is too short for the laptop, I'll get mugged if I use it on the subway, and I doubt I'll need it during class). I'm thinking the Blackberry 7250, the Treo 650, or the Treo 700 from Verizon. But I don't actually need Internet/email access during the commute, and hey, EV-DO's pretty expensive. Instead, I want to be able to write emails with a handheld with a full keyboard and then send them out from my iMac when I get home. (Why email? Because I find that I don't write a lot of email anymore because of the kazillion distractions and tasks that are in front of me when I'm using my computer. I used to write really long and eloquent emails back in the day. Not anymore.) Does this make sense? I don't really know anybody with these devices (most of my friends are Luddites), and most stores don't have working hands-on demo units (*sigh*, spoiled by the Apple Store). I don't even know if I can go into VerizonWireless and demand such an arrangement. (To complicate things further, my current phone's under a family plan!) Maybe it would make more sense to buy a used Palm or an old Blackberry and use it solely as a PDA. But then I'll have to carry that with my cell phone AND my iPod. Any suggestions?
