To add my $0.02 (although probably more like $700-1000), imho the points raised in the original post by Acill are valid.
I'm one of those people slowly returning because of all the news floating about and at this point I have the choice of either going for a Peg with MOS (which look lovely) or an A1 to run Linux.
And seeing as I already have plenty of machines running that my obvious choice at the moment is to go for a Pegasos. Later on if and when AOS4 is released I may consider getting an A1 IF it's good enough and I'm not totally hooked on MOS by then.
