I've got a scanner, Zip100 USB drive, MS sidewinder gamepad (game port), MS Precision 2 joystick, and a Palm VIIx with serial adapter.
 
Of course, I really don't even use this stuff. I bought the joystick for playing descent 3---which I haven't installed since I used Win2k, LOL. $50 down right their ;( I also have two PC's I'm not using much...well that fileserver is kinda important.

THE ONE WHO DIES WITH THE MOST TOYS WINS
 
--On the dive side "The Aladin Air-Z is a wrist-mounted, interactive dive computer with a remote tank mounted transmitter" Weeeell, I don't really hook it up that much but I could...
 

 
--A Sony DSC-P5 3,2 megapixel digital camera, my favourite gadget. Its small, takes great pictures and you can get a underwater kit although that little piece of acrylic seem ridciously expensive
 

 
--My Palm m500, courtesy of my employer...
 
--A Canon D660 Scanner - I really like the thing, after owning a HP scanner and having to fight with their drivers this one is fantastic.
 
--Two printers (Laserjet and Inkjet)

Real fun

Rrrr Right, forgot the phone: Nokia 6210

I was going to get the hoseless comp by Aeris, but I liked the layout of this one a lot better, plus I didn't need to have a separate compass to fiddle with. Nice comp tho.
 
I have a Nikon CoolPix 800 Digital Camera as well, just didn't think to mention it. Oh, and 2 servers and a second workstation, but I don't really classify them as gadgets. For some reason I forgot to post this little guy too:
 

 
That's a Spacetec SpaceORB 360 6 Degrees of Freedom (DOF) controller. I got it with Forsaken when I pre-ordered that bad boy a while ago. Unfortunately, Spacetec was bought out by Labtec and the controller was eventually killed off (they still make the CAD/CAM desktop units that you may have seen elsewhere though, but under another name) Over at Birdman's they have new drivers that will enable most of them to work in Win2K and WinXP.

amond the many cables that run off from the back of my box:
 
1. an Ericsson T65 (throught USB cable)
2. a Nokia 6210 (through serial cable)
3. an old Harman/Kardon amplifier, a Yamaha K340 cassette deck and a Rega 2 Planar vynil 33 1/3 rpm deck (enables me to write from/to cassettes and i still love vinyl LPs!)
4. an Epson 740 printer wouldn't qualify for unusual, would it? So, I'll through in a dot matrix Star LC 24-10!!!
5. Sidewinder Force Feedback joystick, Freestyle Pro USB pad
6. Zip 100 external (is there a way to convert a parallel port to USB? this thing is EVER so slow!)
7. RF antenna for my WinTV
 
that's all for now.......
