Give us some feedback once you get it, GPS/WIFI issues if any, screen, etc.
Do you know if yours comes with ICS preloaded?
So I've received the device and in comparison to other Android tablets I've used, namely, Galaxy Tab and Motorola Xoom, this thing rocks. The quad core processor gives Android the performance it deserves. I always found the Galaxy and Xoom to be occasionally disappointing in performance compared to the iPad. The Prime is buttery smooth no matter what you are doing.
Mine wasn't preloaded with ICS but as soon as I booted it up it began downloading the firmware update and I was on ICS in no time.
Haven't tested the GPS yet, as I mentioned above I didn't get this as a navigation device

My Garmin and GSII serve me perfectly well for navigation.
I also haven't had any of the reported Wifi issues. I sit quite far from my router in a location that several devices drop signal, including 3 Wifi cards I bought for my pc before finally running cable. The Transformer Prime and my laptop never drop signal, so I am very happy about that.
Display is incredible, very crisp and the colours are superb. The brightness is truly in its own class...
Love having a tablet, and if anyone has the option to get one of these I highly recommend it over current competitors.
