Just picked up another board from Microcenter. Two of the location had few in stock.
hah! Good to know. Which location?
Check the website. The location drop down is on the top.
http://www.microcenter.com/product/431730/Jetson_TK1_DEV_Board#
e.g.
Greater Atlanta/Marietta Micro Center - 1
Greater Atlanta/Duluth Micro Center - 2
Denver/Denver Tech Center Micro Center - 1
Chicagoland/Central Micro Center - 2
Chicagoland/Westmont Micro Center - 3
Somebody has messed up badly because there are still pre-orders that have not shipped and NVidia is claiming that they do not even know when the board will be in stock.
