I can live without being able to edit animation frames, being able to view 3D objects, being able to edit HDRI files, et al., but these things are probly vital to some folks. when ya say it's slow-loading, can ya give us times for 5.5 and cs3? in my case, with various other apps running, it takes approx. 15 seconds to load. APS 4 takes 6 seconds, so I reckon if I had 5.5, it might take about 8 seconds.
