Okay, the time has come to upgrade from my trusty blue & white G3 tower and CRT monitor. I've hit the upgrade ceiling on my G3 and the CRT is a space hog and no longer sharp. I'm torn between upgrading to either: 1) A mac pro tower with a desktop 20/23" LCD screen (no room for a 30") OR 2) A 17" MacBook Pro, possibly with an additional external desktop LCD screen for photo work. I work in graphic design and I'm on the path to doing a lot of photographic work, with Aperture as an option. I work mostly at home and don't travel much with my gear. But I'm trying to plan ahead, and a portable might come in handy traveling to potential clients and showing them work. The smaller footprint of a MacBook Pro at home is also attractive. For color work, I'll need an external monitor regardless if I go with tower or laptop. Anyway, I'd just like to hear from other owners.. perhaps those who have sworn off towers and moved exclusively to laptops... is it fast enough for your work? What is your work? Or, tower owners chime in and say why you prefer it over a portable. If you have any recommended configurations, I'd love to hear that as well. cheers!
