I don't recall having to reflash the BIOS on my Windows PC when a bit of beta software went wrong. In fact, I've never even had to re-install Windows to fix a problem - and I've used a lot of beta-quality Windows software since Windows 1.0. I've certainly never been concerned that my hardware might need to be sent in for repair. I think it was a design error for the battery charging management routine not to be in ROM firmware. That's why I'm unhappy with Nokia. I don't know what it was about the Mediabox installation that broke it - does it matter?
