The XMB kinda doesn't allow you to get lost, you're always at the "crossroads" of the main menu or sub menu and the selection, the selected item always the one just below the main or sub row, so extra highlighting of the selected item would be mostly just visual candy.
The photo and music files are highlighted by making the selected item bigger than the others.
The visibility does depend on the background though. Not so with the default backgrounds as much as user wallpapers. So selecting the colour of the fonts and icons would be nice (even two colour fonts, with a different colour outline or shadow).
The XMB is clearly designed with the console pad in mind, using it with a mouse would make the experience totally different, i.e. very bad.
This makes me wonder, will it be kinda annoying if you are using a function that benefits greatly from a kb and mouse, like webbrowsing, you'd still might prefer to use the pad (SIXAXIS? Is it the official name now?) for XMB functions and things like switching browser tabs, using the browser menu and falling back to XMB.
Switching back and forth from kb and mouse to pad could become cumbersome.
Font is too smal to be functional imo. I've the same TV and I know it will be unreadable from where I sit (2 meters away from the screen), let's not even talk about SDTV.
It's got the icons, so once you learn them you no longer need to read the text.
Besides, I think the text as it is is already bigger than text in many games. If you can't read it, how can you play the games?
With SD displays, it could scale them automatically, like in Windows it makkes the icons and fonts bigger if you select 800 x 600 instead of 1280 x 1024.
Still, it won't hurt if they give you the choise.
