I really wanted one ... Test drove it but wasn't THAT impressed. I tried a new one when it came out and a used one with 100K a few weeks ago.
The V8 feels underpowered or detuned. I don't think it is that much of an upgrade from the Explorer below in terms of power. It is no sports truck.
Also, they tend to break exhaust studs and it is a difficult repair. Not sure if it is taken care of by 2010, may not be an issue.
