Windows 8 is Enough? Microsoft OS Family Gets Confusing

Windows 8 is Enough? Microsoft OS Family Gets Confusing

Microsoft mentioned that Windows 8 may show up in 2011.
It will support USB 3.0 and bluetooth 3.0 and more functions.
The speed of Windows 8 booting up is very fast just in a few seconds.
Also, the capacity of Windows 8 is smaller than Windows 7.
If someone hadn't started to use Windows 7 yet, they might use Windows 8.
Microsoft thought that thoese people may choose Windows 8 instead of Windows 7.
In my opinion, I will still use Windows 7 for a couple of years.
My laptop is pretty new just bought a couple of months. The speed of system operation is very fast.
Also, USB 3.0 and Bluetooth 3.0 I think I probably don't need to use them yet.
It's still not very common yet.
