“If Microsoft is going to do hardware business, what should we do? Should we still rely on Microsoft, or should we find other alternatives?”
Yes! I recommend Debian GNU/Linux. In addition to the limited abilities of M$’s software you get a diverse set of applications for client and server and a wonderful software management system. Spend money on advertising instead of propping up M$’s bank account and you will be rewarded, Acer. Other OEMs, take note. If Acer cuts its cost per PC by $100, what will happen to your market-share?
