Linux Appliances

Has anyone else noticed the proliferation of little Linux appliances? The latest couple that have been submitted are the PIA (which runs on a Celeron and looks to be available for $300). The other is from Indrema which is still vapor, but with things like a wireless keyboard and an SVHS port, it looks like a cool game box. Rumored release for it is November with a sub $500 price tag. These guys are getting close to what the NetWinders wanted to be a year ago ... What else does the Linux appliance future hold?
