Based on the draft photo, this thing is an abomination.

We could all do with a higher capacity batter but not at this price (either financial or size/weight/looks/functional) - it doesn't tick any of my boxes, other than that for capacity.

Let's see... no kickstand, cheap looking camera cover, and ridiculous thickness - I had hoped they would just square off the hump on the back of the N900 making it totally flat and no thicker than the camera section alread is, ie. just a couple of extra mm's thickness. But this is waaaay too much additional thickness.

Then again, it's just a draft photo - let's hope it's a very bad and completely unrepresentative draft photo!

If it's not, I'll just hold out for a Powermat Powerpak battery.

I'll be happy keeping my N900 fully charged just by plopping it down onto a Powermat on my desk while at work (the "oncharge" system sound will then become very annoying and have to go - I can feel another "enhancement" bug report coming just for that) and same when at home. By the time I leave work in the evening the N900 will always be fully charged as it's been topping up throughout the day.

I think the Powermat Powerpaks are due in June, and hopefully the N900 will be supported.

I can only imagine the Mugen battery will appeal to hardcore types who might not go near a power socket for a day or so.
