Sold my 17" Macbook Pro unibody tonight to get an i7 version. I'm wondering if I should grab a 15" with hi-res option, or save a little more for another 17". I've been using 1920x1200 for years now, so I'm used to it, but I think I can get used to 1680x1050. Does anyone know if the 15" hi-res versions are on display at Apple stores? Gonna start the hunt tomorrow but figured I'd ask. I worked my way up to a 17" before getting it. Started with 13" but couldn't stand the res, then got a 15" (1440x900) and didn't really like it either. I feel like 1680x1050 is tolerable but I'm not sure. Anyone go from a 17" to 15"?
