I had no trouble with Vista, I liked it. Now Windows 8 SUCKS! I HATE it.
When Vista was first pushed out, it failed to transition the XP Home Edition user in a familiar-enough way. But now, with the passage of time, Vista Service Pack 2 installed on a computer built for Vista seems to work very nicely. Not all XP computers were ready for totally successful upgrade to Vista or 7. Many users were led to believe it was easy to upgrade their old Presario or Optiplex to Vista and 7.
