Funny thing is I had a 17-20 page rant over here with several people arguing me down how good Vista was when it first came out. It was my fault they said. Where are those people now?
I think Vista is pretty darn good to be honest NOW! It is like that car that was a lemon and after taking it back to the dealer 100 times they fixed all the recalls and warranty issues.
Basically, they (Microsoft) back-ported the Windows 7 stuff somewhat to Vista. At least many of the updates etc. The drivers were the issue when it first came out. I tried to run it on an AMD Athlon 64 with NForce Chipset an Nvidia Card, and it was HELL. The development machines were Intel with Intel Chip-sets and ATI Graphics... It probably ran fine on those.
It was probably 1 year + for Stable Nvidia Graphics Drivers! It was SO bad clicking the Start Button would paint the Start Menu in the wrong place. The graphics driver would crash with balloon pop-ups... It would BSOD randomly, and it could NOT go to sleep and wake-up!
I could NOT get drivers for my printer or scanner either.
^^^^^^^^^^^ EVERYTHING ABOVE...... FIXED.
Windows Vista is 95% as Stable & Reliable as Windows 7 if not more. It works with MOST Windows 7 drivers just like 7 works with Vista drivers...
Windows Vista is VASTLY SUPERIOR to Windows XP in deployment, WIM imaging, etc. It is VASTLY SUPERIOR to in a Domain to Windows XP... It supports Group Policy Preferences, Shadow Copies, etc... Right out of the Box.
Trust me... Windows Vista vastly outclasses XP in every measurable way from my perspective as a Network Administrator.
