I purchased my base model unibody MBP in October 2008. It's the 2.4GHz model with 250Gb HDD, 2Gb RAM, and the express card slot. I use OS X for Aperture and photoshop, along with web browsing, itunes, etc. I run Windows XP with BootCamp for CAD and rendering software. I've got two main problems: - The first is slowness, most notably with Aperture, and also with my CAD package on Windows. I think this is probably a RAM issue, so upgrading to 4Gb seems like a no-brainer. Unfortunately, my early unibody (5,1) can't handle 8Gb, and 6 doesn't seem worth it ($300 vs $80 for 4Gb). - The second is hard drive space. I already keep all my movies and most of my music on an external drive, but with lots of RAW images and CAD files, plus the two partitions, I'm now at that painful point of constantly rooting through my files to keep a gig or two free on both the windows partition and the mac partition. So, a 500Gb 7200 RPM drive seems like a no-brainer at $110. I've also done some reading on an SSD ExpressCard as boot drive, notably: http://forums.macrumors.com/showthread.php?t=714310 http://forums.macnn.com/69/mac-notebooks/394126/best-config-48gb-expresscard-ssd-320gb/ http://www.ipodobserver.com/ipo/forums/viewthread/76644/#495993 It seems like a great way to get more speed out of the OS (especially Snow Leopard), and, as a bonus, it frees up 25+Gb of hard drive space. I was all set to jump on this, until I went to check out at NewEgg. With taxes and shipping, my bill is up to $392. My computer is worth perhaps $1300-$1400 at this point, so pumping $400 into it makes me wonder if I've got the wrong device to begin with. Why not sell the laptop and pick up a refurb iMac for less money? I can get 2.93Ghz/4Gb/640Gb for $1279. losing the laptop could be a painful transition, obviously. But I'm pretty well planning on getting a crunchpad, or apple tablet, or similar, once it's available. Hopefully that will smooth the loss of laptop portability. Can someone help me out here? Am I going to get the performance I need out of the three upgrades above, and is it really worth 400 bones? Has anyone out there already gone through with a switch to iMac, or with UMBP upgrades similar to what I've outlined?
