But no hardware vendors are going to care too much about loosing the 1% of the market that Linux represents. That's a big gamble hoping that they will care.

You should be glad that Microsoft are driving a solution to this issue. Security is after all a much bigger problem for Linux than it is for current Windows versions.

I note ~ 200 vulnerabiities in Windows 7 versus ~ 3500 in SUSE 10 (according to Secunia).
