I'm giving it a 5 myself and I've been testing longer than most people.
But let's be fair. For the last two years people have been complaining that "ATI only supports rpm

" pout pout etc. nVidia's installer looks so nice yeah yeah yeah. I've seen the complaints.
We wanted to provide a more pleasant install experience for these people; one that did not necessarily bypass package management like nVidia's (which is important to many Linux users). This installer is definitely a step in that direction.
35 MB IS too big; no argument, but the size will go down as we look into methods for optimizing it. We're just getting started and there's a lot to look forward to.
I'm sorry the rest of you hate it so much. 1 kinda hurts.
