Well, I bought my Peg back in 2002 for MOS and it is running MOS since
then (all releases from 1.0 (oh, that was difficult to get it up...)
to 1.4.2 and will continue to run MOS. I do absolutely not regret my
purchase (note that my G3 was kind of expensive 580 EUR for the Peg1
mobo).

For the record my setup:

Peg1 g3/600 April 1 (exchanged att he Aachen Show 2002)
3D Club ATI 7000/64 DVI
Maxtor 80 G & Samsung 52x CDRW
and a brilliant Belinea 101751 tft-display

Addendum:
Of course the current situation is not best (well, really not..) but
it could be worse. The door to MOS 1.5 is still open and I strongly
believe that Laire (and BBRV) will not let down MOS. It is Ralph's
baby and he is part of Genesi, I also know that BBRV like MOS very
much and will support it whenever they can.
The statement on genesi.lu tells me exactly that.
