I stand by my original arguement.

Old news.
I don't mind the fact you can't remove.

Built in battery on small gadgets have become standard. (ask apple)

Be sure to thank anyone that has ever pirated software on the PSP for this.

There's better longer lasting batteries I can buy for the PSP?

Few things I want to know...

How's the warranty?
How much would it be to send it in for a new battery out of warranty?

So no more piracy for psp go?

I rather get a 3000 now.

Built in batteries really aren't all the bad, I've never had an issue with my controllers or ipods, or any other device with a built in batter.

Well yeah, but its a damper on the people that want to improve their stuff.

I honestly forgot if the battery life in the psp go is longer than the previous one and if it is I wonder by how much? That's the only thing in my humble opinion that would warrant a built in battery if the battery life is significantly longer.
