My geek-jiblets are getting goosebumps!
Marvell recently launched a really funky type of computer, one that is fully contained within the smallest form factor I have seen to date: a plug.

Plug it into a wall socket. Run a single CAT5e cable into it and a USB harddisk. A fully functioning Debian-based Linux server at your disposal.
It runs on Marvell’s own system-on-chip, the Kirkwood series, with a 1.2GHz Sheeva CPU, 512MB of RAM and 512MB of flash storage. There’s support for Gigabit ethernet and even USB 2.0.
I think the best feature of this barebones PC is the USB 2.0 port. Attach that to an externally-powered USB hub and the USB world is its oyster. This little plug can turn a USB harddisk into a NAS and USB printer into a network printer. Add LAMP and and an SSH or FTP server, and it’s all set! Of course, all this is possible because of the OS. Debian-based linux is the only form of linux I actually know, which makes this quite desirable for me. This is mainly due to all the rubbish I tried with Ubuntu. Thus, all my linux knowledge is purely Ubuntu-based. I really should expand my Linux horizons.
However, there isn’t much mention of price at this point. TG Daily’s report mentioned a US$99 “developer version”. I have no idea what’s so special about it. However, the eventual target price for this is US$49, which is actually a great price point for this. Of course, it’s an “eventual target price” at this point, so there is no known availability or projected date. Bummer.
If Marvell would really sell it at US$49, I wouldn’t mind ordering one right now!
