I'm thinking (really) about getting one of these:
They pop up on ebay every now and then, found one in the UK for like $30. They have serial port adapters. Runs an MS-DOS compatible OS. I'm all about 1991 tech.
I could type notes on it, which is all I ever would use a netbook for. Transfer to my PC via a serial to USB cable and telnet.
I'm also jonesin to find an old 80's GRiD laptop for fun. They are pricey even today though.
