The PlayStation Portable Go won’t be available in Blighty for several weeks yet, but images of a dismantled model have already appeared online.

I expect that there will be *plenty* of units available in the stores then.
Looks like they embedded the battery in hope to keep it away from those "pandorized" batteries enabling custom firmwares. This is a bad trend (Apple does that too on their new MacBooks) because batteries don't last forever and it makes the PSP useless when the battery is dead, as it wouldn't be worthwhile to replace it at that time .
