I know this has been discussed before, but I'm still ignorantly unclear as to which tasks upgrading the Mini hardrive to 5400 (or 7200) will show the greatest speed differences (for those of us who bought prior to tomorrow's possible changes I already have 1 g RAM. Will I notice differences in: internet surfing, opening aps, using powerpoint (way too slow), etc. or is it primarily with gaming, which I don't do? Thanks for your expertise. Trying to decide if it's worth the $$$ for me.
