An essential.
Be sure to buy one of these for playing at home, since you'll want to conserve your batteries.
You don't have to worry about quick draining on high CPU clock speeds, so you can play gaming at it's finest quality!

This, plus a TV-out cable = home video player, it's great.

It's worth noting that the european style cord can be switched with a british style cord, so long as it has the same end that fits into the power block. I'm using the plug from my DVD player that I NEVER use, absolutely fine. :)

Very cool
to be able to enjoy playing so long with sound on TV :)
