Obviously they are not the best on the market, compared to OCZ, etc. However, you likely notice the difference in normal use? (i.e. web browsing, photoshop, email, imovie)? Is the lack of TRIM support really as bad as people make it sound? The $90 upgrade for 15" is tempting, but I was originally going to get a OCZ Vertex 2 for my boot - and leave the default 500GB 7200rpm for storage. Thoughts?
