Have I missed out not buying one of these?

I haven't had any need for a media player as I have almost every type going.
If anything I wouldn't mind playing about with one but can't most of this be done on a pc?

i looked at NFC / RFID which seems interesting along with home automation but thinking the kit price would soon mount up making it an expensive toy.

what do you use yours for and how much use have you actually had out of it?
