So, I'm looking at two models of Apple laptop: the 1.5 GHz 15" PB and the 1.33 GHz 12" PB. To lay out the specs: 15" PowerBook 80 GB HD at 4200 rpm Combo drive ATI Radeon 9700 Mobility, 128 MB of VRAM 512 MB of RAM Cost: $2209 12" PowerBook 80 GB HD at 5400 rpm Combo drive NVIDIA GeForce FX GO 5200, 64 MB of VRAM 256 MB of RAM Cost: $1512 First off, my situation: I am starting my first year of college in a month, as a computer science student. I plan to do the general things with my laptop: surf the web, listen to music, organize photos, write papers, and code programs, but I don't plan to shoot video, burn DVD's, or work with graphics heavily. I won't be into gaming too much, though I would like to play Halo. I'm not too concerned with portability, and I have a 17" CRT I can use as an external monitor. I plan to get more RAM from a 3rd party later if I go with the 12". Now, the questions: 1) I'm wondering just how much the lessened screen real estate of the 12" will be if I don't plan on doing graphics work. Note that I have an external monitor and with Exposé I can stack windows easily enough. 2) I'll be learning computer programming, and I'll be compiling programs and all that, and I'm wondering how much of a difference it'd make to have the 1.5 GHz model instead of the 1.33 GHz. It's worth noting that I could probably set up my current 450 Sawtooth G4 as part of a build farm that could also include a 300 MHz G3 and a 700 MHz G4 iMac. 3) It seems to me that the optional features you get with the 15" model (gigabit ethernet, FW 800, backlit keyboard, PC card port) are only useful if you plan to be exchanging large files regularly, backing up to an external drive, working in the dark, or if you're in situations which would require the use of other PCMCIA devices, and I don't see myself doing these very often at all. Is there anything I'm overlooking? 4) Video memory and the GPU: if the only graphics card intensive program I plan to use is Halo, and I don't demand an excellent picture, how much of a performance boost would I see with 128 MB? Speaking of which, didn't the upgrade to 128 MB use to cost $50? Because it looks like it costs $90 now. Also, how much better is the ATI card, and is this important to me? 5) How important is HD rpm? Probably the only thing that's keeping me from just going with the 15" is cost. It's right at the upper limit of what I'm willing to pay now, while the 12" is far more affordable. So which should it be?
