I picked one up last week from Expansys. If you have a search they sell it bundled with a 1GB RS-MMC card for about 50p extra.
It is a great little unit and was purchased with the hope of being a replacement for my laptop on short trips but I am unable to log in to ba.com with it. Whenever I click in to the BA Exec Number field it causes the page to refresh.
The main reason I take the laptop away is for OLCI!
If anyone has anyluck then let me know!
