I'm using a TF300. I would love to see 2GB of RAM in a later version (Such as the TF700) It doesn't have the aluminum reception issues but the initial ICS build can run into a few bugs when it comes to certain TEGRA3 games not working.
GTAIII, awaiting refund, developer has told me they are not currently supporting my device but the TF101 and TF201prime work ATM
Renaissance Blood THD freezes within 5 seconds of the game beginning (reminds me of a bad VHS tracking issue that hangs) The development team is currently trying to find a fix for me.
Other than the random "program is not responding" click wait or ok bug, I haven't had any issues. Out of the box it works with most any usb game controller (felt a bit nostalgic and played a little sonic)
I love the HDMI output but noticed some lag issues when multitasking and playing high end games.
