I'm actually a big fan of Sony's XMB, but if I didn't own a large plasma, it would be pretty tough to read. Luckily, some interface tweaks are coming in Sony's 3.0 firmware to address the problem.
Specifically, a new "What's New" folder replaces the Information Board. Highlighting this folder produces large icon pop-ups that will link you straight to a recently played game or a spot on the web. This icon system is used in the PS Store as well, connecting you to video content and games with a bit more ease.
Themes, too, are seeing a bit of a revamp, including premium options with avatars and animated backdrops. Yeah, premium themes copy Microsoft a bit, but that's not necessarily bad for anyone.
