I got my 101 16GB last week.
Updated the firmware.
Installed the android market hack (now have full market access)
Installed Flash (still a bit laggy until the optimized version is released by archos)
Installed LauncherPro Plus.
its fast, smooth and the battery easily lasts a day and a half under heavy use.
I can access my pc network and view/play shared files.
I can output to my monitor/tv via hdmi.
I can control the device with a Wii controller via bluetooth!
I have only found 2 apps so far that refuse to work on the 101
'extended controls' and 'mini info'
its fantastic, and definately value for money.
lose the task killer...!
