I think Mr Magic needs to listen to potential customers?

Microsoft are learning the hard way with their loosing battle in the mobile computing stakes for being too short sighted. Apple for example allows you to reload it's software on many devices and remembers 'you' from your account not certificates. Android the same as Apple for most software in the main.

It would have been simpler to have said thank you for the suggestion and say you will go away and look at it. Trying to defend on here is suicide especially when this forum probably covers the majority of your potential market.

PS

I find CAMBAM offer this service (i know not 3D), they listen to their users and are very friendly :-)
