That what I call a nice little USB key memory. Let’s imagine carrying with you not only your precious data “My Precious!” but all you email and your favorite web browser with all your bookmarks. This is feasible thanks to Hagiwara and Thunderbird plus FireFox. Well you understood well both of them, FireFox & Thunderbird are in the memory key and will allow you to use any computer as your one in order to surf on Akihabara News and write or receive emails.
