Lik-Sang gets some hands on time with the First Generation Sony PSP Compact Flash + SD + MMC Card Adapters. They are the Neo 2in1 (ships in 1 to 2 weeks), Neo 4in1 (ships in 4-6 weeks) and the Neo 5in1 Pad (ships in 4 to 6 weeks).

Definitely a good read if you are looking for some alternatives to what is already out on the market.
