REALLY enjoying the sorting features. I'll get to them in a second.
But I also love how you can darken your backgrounds up to 5 shades!

Seriously! I didn't think they'd do that!
Also, it's interesting how Manichi no Isso, or whatever that free PSN Cat game is, doesn't let you sort it away into albums. Everything else does.
By the way, if you want to save time (And you don't have a keyboard) you can album everything with 'D' then later JUST RENAME THE FOLDER and all the items inside get titled correctly.
Info board doesn't seem too bad, I can handle it. (If you don't like it, at least you can turn it off, unlike with the 360 and the huge ads)
However, can't try remote play boot because I'm on 3.71 M33-2, but I set it up to. I don't like how I had to enable auto-login to do it. :-/ Seems like it should handle multiple PSPs on multiple accounts on a single PS3, for the family. Oh well. Not a big deal.
Default theme is nice. Hopefully it's easy to import our own, just like on the PSP. And you can group EVERYTHING, even game saves. Memory card sorting didn't change at all, though, didn't really need to.
PSN network category is awfully lonely.
Edit:
I wonder if it made Buzz not crash anymore or Singstar work with swapdiscs... Hmm. I'll go try!
