Arrr .. me too....
3PC's running Linux
Also 1x NAS running linux.
And my PS3 ... although the Suse install was broken about 6 months ago through a firmware update ... and I haven't bothered to fix it yet - Linux on a S3 has limited uses for the average person, other than bragging rights
Although ... there's a possibility that the iphone is running a variant of linux .... and my adsl modem, 3x access points, VOIP ata, 3x network switches (I doubt the switches & AP's though).
