I'll agree vista is jolly decent but drivers for particular products are still surfacing belive it or not only very slowly and companies Isd departments then take ages testing them.
I have found they are increasinly very cautious to make any major changes if things are working as heads only roll if things go
It will be intresting how the iphone and gphone get on with the public in the next few years as they are both browser based.
If they take off and the isps start to get joe public intrested in a cheap pc (ala like their phone free or dead cheap with it being upgraded after a few years.) the phone companies now personailse the os of the phone for their own reasons, so if the isps follow the same line they willl do the same in tie ups with ms and apple im sure. A good way for the os/isp companies to keep control of their market is to make the os either fully or partly server based.
In fact in the media a week or two ago a uk goverment department were looking at ways to save engery nationally and one was to have people have thin clients in the home with large servers accessed via internet (ie isps and phone companies will make money and bankroll the scheme along with the o/s companies chosen)
The engery and resource savings will probaly stop the national goverments or the EU getting involved in any real debate about if its right or wrong they know it will help them reach their co2 and waste product levels.
This would be a few years off and some people would not like it, but most people don't really care what pc or os they have as long as they can browse the web, vist facespace(or whatever) Have office type software etc. Microsoft are already talking about a adds based version of works which i guess would be free so would be distrubuted via the internet anyway.
Where that leaves other parts of the world im not so sure already limited versions of os are avaiable at cheaper prices in asia.
