Damn...I am just driving myself nuts over whether to get the 12 vs 15 PB! I've read through the old posts and they have been very helpful...but cannot seem to make a decision that sticks for more than a few hours. I'm going to law school next year in NYC and wanted to retire my old thinkpad and not bring up my pc (b/c of space reasons and I'm sick of pc's). I'm going to just use my PB in my apt and for law school. I'm going to be doing minor photo editing, ipod stuff, lots of researching and writing, etc. I want the portability (I think the 15 is going to be portable enough), so the 12 would be ideal. However, each time I see the screen of the 15 and compare the weights (not the dimensions) of the 2 models...there doesn't seem to be much of a difference. The options I'm mulling over are: 1. Get the 12 inch with the SD and upgrade the HD to the 5400. Eventually purchase an LCD monitor for the apartment when I move to NYC. 2. Get the 15 inch with the SD and upgrade the HD to the 5400. No need for the monitor and just compromise the minor difference in portability for a better screen when I'm not in the apt. 3. Same as 1 or 2 but with a combo drive and pick up an external dvd drive. HELP!! (Geez....if all my decisions involved such fun things to trivialize about.) I do appreciate all of your suggestions and really respect your input. Thanks!
