Hmm, good question.<p><pre><code> Two cars: probably 50 in one and 20 in the other.
iMac including internal/external peripherals: 10?
2 iDevices: 8 more (CPU, touch controller, GSM modules?)
My kitchen probably has 10-20 in various appliances.
Kids toys and video games: probably 40-50.
Cameras: 4-5
Almost every SD card has an ARM core, so 30 more there.
TV sets, Sat decoder, DVR: another 10?

I'd say 200 easily. I'd guess most households are somewhere around this number.
My list:<p>1 Intel i72700k desktop (4c),
1 Intel i72670qm HP laptop (4c),
1 Intel i3330m Acer laptop (2c),
1 AMD Phenom II x6 1100t desktop (6c),
1 AMD Phenom II x4 830 desktop (4c),
1 AMD C60 Acer laptop (2c),
1 Tegra II Viewsonic gtablet (1c),
1 Tegra II Droid X phone (1c),
and an ARM in the Raspberry Pi (1c).<p>Looks like I notch in at 25. I'm in a technology/business related research field.
I have dozens of microcontrollers for my own development projects, and I would estimate ~100 in various consumer devices.<p>Something I'm looking for an excuse to buy would add 288 cores with a single PCB:<p><a href="http://www.greenarraychips.com/home/products/" rel="nofollow">http://www.greenarraychips.com/home/products/</a>
If we're only counting x86/ARM, 10.<p><pre><code> x86:
* Quad core PC
* Dual core Macbook
ARM:
* Two dual-core android devices (phone, tablet)
</code></pre>
Course, there's the PPC Xbox 360.
I have no idea what's in my internet blu-ray player.. I'd bet it's ARM.
12:
4 iMac
4 PC
2 Macbook Air
2 iPhone<p>Technically I also own 16x4 core servers in Germany as well, totalling 76 cores!<p>edit: ps3/wii also, but not sure on the core counts
seven: two dual-core Mac minis, an Atom-based netbook, and a Galaxy Nexus...<p>...plus the ones in my synthesizer, drum machine, and camera, I suppose. There's probably one in the router, too.
