I've been reading all the SSD threads and I'm a bit confused by all the brands, prices, issues, etc. and wondering if it's worth the upgrade for me. I've got about $100-300 to spend on this upgrade. Primary use for my macbook (2.2GHZ intel core 2 duo , 4GB RAM installed, 500GB 5400rpm harddrive installed) is running Adobe Lightroom and Photoshop- I am a photographer and after a large photo shoot I may need to upload and edit 100's of photos quickly and easily. Currently, I am not getting the best performance out of my mac's 5400rpm drive. how much faster would this be on an SSD than say, a new 7200RPM drive? what are the ssd drives I should be looking at in my price range? should I wait for the prices to come down a bit and go with a 7200rpm drive, for now?
