Installation is the easiest yet that I have dealt with for a server product.  As far as stability is concerned I have had no problems whatsoever with SharePoint flaking out or something screwy going on.  It just works�.  Integration with Office XP is great and really adds value to your investment of Office Technologies.  Recoverability for SharePoint gets a C.  I have never like recovering FrontPage webs and SharePoint complicates the matter even more.  You won�t be able to change the hierarchy of your webs once you set them up the first time.  In other words if you have subwebs that utilize Team Services you won�t be able to move them to a different directory or the root level.  Just something to keep in mind to make sure you do it the way you want it the first time.  Otherwise it�s just easier to scratch the web and start anew.  For the price of FrontPage Team Services is definitely a bargain.  Overall I give it an A.  Team Services is featured packed and I am very impressed with the product as this is just a 1.0 release (and people say Microsoft can�t get it right on the first try).  It will be very exciting to see how this product matures over time.
