Just got mine too and I'm in the process of installing programs and copying lots and lots of applications file.
Here is brief run down from a diehard Thinkpad user and former owner of a D810.
The keyboard and trackpoint are extremely important to me and I have to say, they have made some HUGE improvements. The trackpoint is as good as that found on a Thinkpad right down to a flattening of the rubber cover with a textured top to make it comfortable to use for extended periods. The buttons for the trackpoint are vastly improved and more ergonomic to use.
I love the feel of the keyboard - perhaps even better than that of a Thinkpad. I'll have to see how it is after a little breakin period, but it is very very nice.
Weight is excellent for a 15.4 inch laptop. I have a Sony FE570 and it is comparable. The FE570 is the lightest weight 15.4 inch laptop I've ever used.
LCD is very good... I actually think it could be brighter, but keep in mind, it's not a glossy screen.
The new form factor is another HUGE plus. Much nice to deal with and I am so glad I got the 820 instead of the 620.
I'll take some pics tonight and get them uploaded... but as far as I'm concerned right now, the Thinkpad is going on the back burner... perhaps even ebay.
I got an EVDO card so tomorrow I call Verizion to see how to get that working.
