I just installed it, and I have to be honest it's more than comical how long it took them to figure out to blur out the background so you could read whatever it is you're trying to read (depending on your background, of course) but nonetheless. Same goes for the large text size although I never really had much of a problem with the original print. Two, apparently Sony finds it impossible to allow the PS3 to play music in the background. If you want to listen to music while you're doing whatever it is you (were) doing on the XMB, I hope that's all you want to do.
The image scaling has always annoyed me and apparently it hasn't been fixed. How you can see the image in full bloom when you're just looking at is perfect, but how it's scaled larger once it's set, and then scaled even more once you get back to the main menu is frustrating - I'm referring to images shared from your PC that you'd use as a background just so no one is confused. Call me harsh, call me whatever you wish to, but you'd think the claim of "The next generation begins with the PS3" Sony would have gotten all of this from the get-go, yet, they continue to shoot themselves in the foot.
One way or another.
