Performance wise, ASUS have nothing to worry about as they've included NVIDIA's quad-core Tegra 3 SoC. The Prime is one of the faster (still!) tablets on the market and with Android 4.1 Jelly Bean thrown into the mix, it's a perfect fit.
It does have its slowdowns here and there, but I found that when I was doing a bunch of I/O, such as saving screenshots for the review, flipping the screen back into landscape and taking another screenshot, etc. But, this is not normal use, so I can't really fault the tablet for that specific issue.
I had no issues with the Prime, compared to the bigger brother, the Transformer Pad Infinity. The Infinity had its issues, here and there at least, but the Prime has been faultless for me. I'm putting this down to the upgraded OS, Jelly Bean. This would be the only change and I'm guessing that is most likely the savior in those issues.
I actually had a better experience on the Prime than I did the Infinity overall, and I, as I said above, have to put this down to Jelly Bean. This is why I love Jelly Bean so much - it improves so much of the Android experience.
The Eee Station is great - bashing away on that keyboard feels fine. Not that I would use a tablet as a professional device, but if it's needed, it's there. ASUS have the "I'm-a-tablet-but-also-a-netbook" market all to themselves right now, with Microsoft really only entering the game with Surface just recently.
The camera on the Prime is just as impressive as it was in the Infinity, and this time my wife took some amazing pictures to show off the Prime's camera muscles.
