I tried to buy mine the week they were released- had to wait a couple weeks. (May 2011.)
The advantage the Transformer has over anything else is the keyboard dock. It doubles the battery life (great for trips) and with a touchpad and keyboard, can make surfing/typing a breeze. Keyboard also has special buttons for the media player, settings, volume, etc...
I too had the "random reboot" after the initial ICS but it hasn't been off in 580hrs, I think the kids let the battery run out..
I love mine and use it quite a lot. Google Play support, Netflix app, office if you really need it (although it's quite clunky/junky).
Look around on ebay and the refurb sites to see what kind of deal you can get. I wasn't too concerned about storage (got the 8GB) but would have liked to go bigger. Oh well, MicroSD cards are easy.
Amazon has a 9ft mini HDMI cable fairly cheap- I use it for watching netflix or other movies from time to time.
