Try living with it for several days or more with all the ThinkPad utilities. I've had my X61t for a couple of weeks now and don't feel that those utilities are causing me any grief. I did an in-place upgrade to Vista Ultimate because I wanted both the business features (especially the full image backup) as well as the entertainment features. In the process I lost several of the ThinkPad utilities and I had to do some fiddling around to get them back. And I did it because they were reasonably well implemented and non-intrusive.
I didn't have to contend with anything I would seriously consider junkware.
How much ram will you have?
