| What is SP1? It is my only browser but I'm not having any problems....uh, yet. |
Service Pack 1. It use to be dont use a 1.0 product, but things are not that simple any more. So the new maxim is wait for Service Pack 1. Unless you like beta testing. 
Everybody who uses Internet Explorer 7.0 has Service Pack 0
After a couple of months Microsoft offers Service Pack 1 for Internet Explorer 7.0, Windows Vista, Office 2007,....
There after a year or 2, Microsoft introduces Service Pack 2, just what they did with Windows XP. After that probably a new Windows.. Some said Windows BlackComb..
When are they going to introduce WINFS? They say it was with Vista, but NO, it's still NTFS..

Longhorn, never exally introduced, just a few beta's,.. Oh well Microsoft want to be the best, by creating software that anyone can use, but how many people use Office 2007 with all the new techniques and new object and new functions?? Not many.. And that shall be also with Office 2008, 2009,....
