I think its opinions verses XP home and XP PRO. At first the net was filled with concernes about Home vs Pro. Most concerns were not proved valid. It is now felt thta both versions are good softwares. And, are "about" the same as I mentioned above. I run XP home on every thing except my test machine which is XP PRO. I was using XP PRO when it was still in beta and in fact predicted several problems (that later proved correct) that would haunt signmakers..
Most of the problems people had was not due to home verses pro. The problems was within the OUTLOOK kernal...
Previous releases of AutoCAD and Studio3D Max would not work under WinXP Home,
Not necessarily true,
The problem with those softs was usually traced to the graphics capabilities on the older video cards.
Bentley Microstation still only asks for: Microsoft Windows® 2000 (SP2 or higher recommended*), Windows XP Professional, Windows NT® 4 (SP6 recommended*), Windows 98 (Second Edition recommended)**, Windows Me**, Windows XP Home Edition.
Catia V5 calls for Windows® 2000/XP Home Edition/XP Pro.
The problem with XP home and win 98 comunicating was "usually" that tcp/ip was not installed or configured correctly.
As far as 5 machine limitations I know of very few that need more than 5 machines. Even win 2K server was sold as a 5 seat license.
In the end, it loos like Home vs Pro will be debated until (longhorn) now named Vista is released.
The average user will not need anything more than XP home. The average user does not use VPN, or use more than 5 machines. The average user does not use dual processor machines either.
I predicted that SP2 was going to be a nightmare for signmakers long before it was released. A few posters here will remember when I posted that the SP2 fiasco was goona happen when they upgraded to SP2..
