If you own a PS3 this is an awesome update....probably the best one for the PSP.  But that's the problem...if you own a PS3.  You can now remotely link to your PS3 over the internet with your PSP and access music/pics/videos on your PS3. If you have your PS3 linked to your PC you can even stream content off the internet to your PS3, to your PSP. And you can now, with the PS3, remotely access the PS store with your PSP and download PS1 games directly to your PSP. 

I'm ticked off that you still can't access the PS store without the PS3.

But the internal buffer allows 2-4 megs and that would be a huge txt file. A 2MB adobe ebook is around 600 pages.

If you convert large books to html you'll want to set up bookmark links to each chapter..otherwise you'll have to scroll through the whole thing to go back to where you left off.

I really wish Sony would support an ebook format myself.
