20 is too many??? (Score:3, Informative)
Anyone who answers LESS than 20 is either very spartan or not counting very carefully. Practically all kitchen appliances, any LCD monitor, any TV, every mobile phone, portable music players, media players, game consoles...all times however many chips are actually in the thing!
I easily got to 25...without even counting the desktop/laptop computers!

There's at least a dozen microprocessors and microcontrollers in the garage/workshop and a couple more in the garden shed, but none yet in the greenhouse. Our technical room alone has about a dozen of the things (server + 5 disks, router, optical switch, 2 ethernet switches, UPS), and there's another dozen-ish in the utility room and kitchen (laundry, sewing machine, heat pump, water heater, ventilation systems, 3 freezers, refrigerator, 2 microwaves, stove). The house also has various digital clocks, thermostats, and wired & wireless sensors. Then there are the actual PCs, of which we have 4 right now, each containing multiple microprocessors (CPU, GPU) and microcontrollers (network, firewire, USB), with 1 printer, 1 multi-function network printer/scanner, another ethernet switch and another 2 UPS boxes. Ah, nearly forgot the living room with its PS3, IPTV digibox, "smart" TV, DVD player, VHS player, and yet another ethernet switch. There are also several mobile devices (6 cellphones, 4 MP3 players, 2 video/MP3 players). I have no idea how many microprocessors are in the cars, but they both have SatNav systems.
Depending how you count, it's getting close to 100 even without the cars' built-in devices.
Poll is to vague - Define "microprocessor" (Score:5, Informative)
so I didn't come up with a number in the hundreds, I chose to assume that:
I came up with the following list:
There may be others, but this is what I'm aware of off the top of my head.
Even by this admittedly conservative definition, I came out in the "too many" camp.

How can anyone be confident that they have 20 or fewer? Between obvious things like computers (typically two or more processors each) and smartphones, there are processors in DVRs, DVD players, MP3 players, notsosmartphones, radios, answering machines, digital picture frames, microwave ovens, clocks, thermostats, and yes probably even some toasters.

Come on folks. EVERY device in your house that has a LED or liquid crystal display has at least one microprocessor in it; probably more than one. Here are a few things to consider in your count:
cell phone(s)
wireless phone (has two; one in the base, one in the handset)
answering machine
microwave oven
DVD player
VCR (some of still have one)
CD player (and even one of these)
MP3 player
Digital clock radio
stove
dishwasher
digital thermometer
bread machine
wrist watch
GPS (we have two)
TV(s)
cable box or satellite dish
calculator(s)
digital camera(s)
Camcorders
programmable thermostat
and, if you have an attached garage (which I assume means its part of your home), your cars have a whole bunch of microprocessors if they're not considered a "classic."
Now go back and count again.
