Bits (and PCs)...
Everyone1 needs a hobby; something to stave off the boredom.
I confess I've always liked gadgets of various kinds, and firmly believe that "He who dies with the most toys, wins" (though I'm not sure what the prize is).
I've described my hi-fi systems here (living room) and here (upstairs reading room), and there are some notes on my video system here. My remaining major lumps of technology (described within this section of 'molehole') are largely related to personal computing. Mind you, the recently acquired Netgear media player bridges neatly between both worlds.
Enter my little hi-tech Aladdin's Cave (via the button above) at your peril.
