I am traveling to New Zealand for a couple months and I was looking at 667 15" PB's and wondering if it would be a good idea to buy one? My price can't go over $800. On ebay I have seen some 667 15" and 867 12" (12" has the 1024 res.). I am worried about the LCD's brightness and wear and tear (which will be different for each PB) I would be using it as a secondary computer to check mail, chat and design websites for relatives in NZ. Can anyone give me some suggestions? Thanks.
