Why I won't be updating to Windows 8 immediately

There has been a lot of hype over Windows 8 and the new interface.  I like Windows and think that it is a solid OS.   That being said there are three reason why I won't update immediately, 

1) The Graphical User Interface.   It is completely different than any previous OS.   Here is a video that show the extent to which some users might be confused.

2) Waiting is always better.   Even with the best tested OS's there are always bugs.  If you wait 6 months you are guaranteed to get  less issues and bugs.

3) Window 8 is built for touch screens.   If you do not have a touch screen, why not wait until the next hardware upgrade and then upgrade.
