Don't get me wrong, we can use Vista with our licensing model, but choose not to. Being the Australian IT Operations Manager (now) for a rather large international corporation, we decided not to use Vista due to the sheer hardware requirement that would be needed to run it. This is an overhead that most corporations would see as a driving factor to not use Vista. There is also the "why change to another operating system, at a major cost of hardware and resources when XP is doing the job that we need"?
If there is extra security features in Vista, they are not normally required in a corporations as most users will not have rights to in applications on their XP system and the anti-virus, firewall and proxy servers will do the rest. This is another reason that corporations do not need Vista and the sales of Vista are down.

There is my 5 cents worth from a bean counter and an implementer... <

I have Vista and all of my programs have very same tab available... Feels like you didn't even bothered to use it. I've never yet to fail a program that I use before and that does not run under Windows Vista 64-bit.

Don't have Vista and don't want it. I was responding to your comments insinuating that Vista shouldn't be responsible for reverse compatibility and that XP wasn't, when it indeed is.<

I thought this is an interesting article on Windows... Basically saying Vista sucks and MS in a big trouble??

Vista doesn't suck, but it's disappointing. But MS is hardly in big trouble, unless you mean they have trouble trying to figure out where to spend all the oceans of cash they have :)

For that matter, MS could declare bankruptcy after spending $800 billion or so, and the federal government would probably bail them out like it did the savings & loans, auto manufacturers, oil companies, etc. Seems like the more money you owe, the more likely that the feds will assist.
The small businessman is treated a bit differently. They tax the crap out of him, harass him with compliance issues (like installing wheelchair ramps, beveled and sloping sidewalks, and handicapped bathrooms). When was the last time you saw someone in a wheelchair delivering a broken tower to a computer repair facility? Have to have safety glass on windows (in case someone breaks in - don't want him to cut himself), etc., etc. They basically do everything possible to force small businessmen to close shop.<

I have switched all of my computers but 1 to vista as well as got siblings who are not computer literate in any way to purchase computers with vista.
They have not had any issues with vista that I keep hearing about. They have all installed Office, Games for kids, and printers and so forth without issue. They didn't have to go out and buy new routers/printers/software just to run on their vista machines.
But I guess they just got lucky but so far dealing with about 7 computers in all with all of them running vista only 1 program wouldn't run tried to install on xp and still wouldn't

As far as saying that MS should make their OS work with older software/hardware this is not the case when people went from VHS to DVD they had to buy all their old VHS ina new format to make them work.

Any new game system for the most part will not play old games my wii will play gamecube but they won't let it play any of the old games like mario and goldeneye. Oh well dang nintendo.<
