Long time without biting... But the name is:

I stopped playing so-called memetic games a long time ago. But I liked this one - Thanks to Nicolás Valcarcel.
So, what are the current names?

Netbook
aikoa (temporary name, /methinks)
Laptop
malenkaya
Work desktop
mosca
Home server
cajita (yes, not very imaginative - it's a Mac Mini)
Main work server
lafa
Virtualization host
pulpo
Work firewall
joma

Other current machines have much less exciting names. Some of the older machines I have named (and with which I worked enough time to remember them) include shmate, lactop, conetontli, tepancuate, tlamantli... And many other long forgotten.
Oh, and... About a pattern? No, don't try to find it. Of course, if you do find it, I'd be delighted to know! :)
