I think this might have been covered in all the knowledge above but i did not see it with a fast scan so just to let you know what i discovered a couple of years ago.

M does have a beta program as I knew of a chap who worked in a dealer who did much of their software and hardware testing on many products.

I would GUESS however that most of the staff do the remainder of the testing and maybe some family and friends - hell you need perks to every job huh!

Perhaps this is why we have so many glitches and perceived problems with the G -series video output. They cannot test every screen and projector on the market and we only remember the ones that complain not the silent hundreds who have a great product.
If it was all so bad I am sure M would have gone away like TAG by now. I do not think that the 25 people on this forum are their income really. hell it took me 3 years to find the forum existed let alone start commenting on it.

my two pence worth, must dash the missus has caught me on the PC over Xmas. tony
