I was one of the first guys here to get a F90BT and I kept it about a month. I loved the unit, hated the bugs and with my 30 day return to ABT winding down, I had to make a decision so I returned the unit and exchanged it for a Kenwood DNX-8120.
Anyway, with the 2.0 update and the way the price on the F90 has plummeted, I pulled the trigger on a new one on Ebay.... with the 25% cashback from Microsoft, it was too good a deal to turn down. I figure I can sell my DNS8120 and actually come out ahead.
So anyway, I guess Ill be reinstalling my F90 next week when/if it shows up. Im excited to see how the unit shakes out now. The 8120 is nice.. its a very solid unit but I miss some of the stuff the Pioneer units offer.. especially the MSN Direct stuff which I used all the time.
