Even though I have a DS & PSP, I take my micro on my commute because I can jack music and ebooks into it and use them at the same time with the GBAMP.
I like the new music function but will we be able to read ebooks on it too. I like to game but on my way home I sometimes want to just read some Terry Pratchett and listen to Tom Waits.
If it can handle that without any extra imported equipment, I'm sold; and I mean 1st in line at launch sold.
