Economy sucks, business dying by the hour and companies still hesitating a move from XP.
Who are Microsoft kidding?
The only way the average consumer upgrades a OS is when they buy a new PC with the latest OS pre-installed and sales of PCs are down.
The consumer generally buys a new PC when the existing one literally dies so anyone who bought a PC is the past 4 years will probably not update for another 4 years. By then we may be looking at Windows 10.
Windows 8. Bad timing, too different, no real added value to Win7. After all Windows 8 is really just an upgrade, not really a whole new OS.
