So.. I've been using an MBP5,1 (2008) happily for a few years now and am just missing out on having a machine I can easily take to work with me. The MBP pretty much sits on its iLevel stand in my room all the time and I don't like the idea of carrying it around because it'd only just fit in my work bag and it's plumbed-in as my "home Mac" by now. As it's also getting on a bit I'm wondering if I should take advantage of this hardware refresh but I'm wondering what the best way is: - Get one of the new MBA's coming out this year. I like the look of them but I don't know what they'll be like as far as performance. - Wait and get a new MBP whenever they're refreshed. Problem is, I might hit the same carrying problem, plus it seems a bit goofy to have my portable machine be more powerful than my in-place one. Is there going to be an hard-disk-less MBP at some point? - Get an iMac and carry the MBP5,1 around as a portable. I'm just not sure about iMacs, though, mainly due to the surprisingly low graphics performance. As I've seen others say it seems daft to have a machine with such a nice high resolution screen and then drive it with a mobile graphics card. Any suggestions?
