How many computers have you got?

My daily drivers are my sig rig or laptop. (iPad and phone too I guess)

I don't touch the 24/7 running machine unless I have to.

Two PCs, one with Windows 7 64bit and Windows 8 Pro 64bit on separate SSDs and the other with Windows 7 64bit and Windows XP on separare HDD's. Then a laptop with Windows 7 32bit on an SSD.

I answered two, referring to my Windows 7 computers, desktop and laptop (specs for both in my profile). But I also have a Motorola phone running Android GingerBread and a Samsung Galaxy Tablet 7.0 Plus running Android Ice Cream Sandwich.

I have too many computers! Not sure I can remember them all but here goes:

Main desktop (homebuilt i7-3770K) - Win 7
Dell Laptop - Win 7
Acer Netbook - Win 7
Galaxy Tab 2 7.0 tablet - Android ICS
Nexus 7 tablet - Android Jelly Bean
Droid Razr phone - Android ICS
Raspberry Pi - Linux
Nokia N800 handheld - Linux (not really used any longer)

I also have several other homebuilt units (3 with Win 7, 1 with Win 8)
I also have a collection of vintage computers (pared down to around 10 now) that mostly run DOS

I work from home so I also have a laptop plus 2 servers for my work.

I think that's all of them, I count 24. (there's probably more)

The count above doesn't include the computers my kids have. My daughters each have an Android smartphone, desktop, netbook and an Android tablet. My son has an Android smartphone, desktop, laptop, netbook and Android tablet.

Lastly, my wife has a netbook.

Wow! 38 (or more) computers in our house. I really need to cut back.

I now have 4 computers, 2 main desktops & 1 reserve desktop with Windows 7 Ultimate & Pro on the main rigs & a fresh install of Win 7 HP on the reserve rig.

The newest computer is an Asus Laptop upgraded to Windows 8 Pro from Windows 7 HP and is also used daily with my 42" TV as a secondary display.

2 in the bedroom, my Wifes laptop, one in the upstairs hallway, 2 in the living room, about 4 in the other bedroom (probably more buried there) & at least 2 in the attic. Some work, some don't...hell, I lost track. And enough parts lying around to probably build at least one working one....

Voted two.
Monitors on the other hand - let's just say when there's another e-recycling drive some of them have to go.
Desktop is still a good built machine, mostly htpc but also a bit of a server for the homegroup when I need it. It received it's probable final upgrade, an ssd not to long ago. W-7 hp.
Recently bought an Asus k53e w/i5 sandy bridge. I realy like it. Slabbed in 8 gigs of Adata and debating a 240 ssd once the warrenty is up. I like the fact I can do most of my computing with it, use it anywhere, at home, at camp, off solar, and use use less then 1/3 the power the desktop chews. The best part about it, w-7 hp not 8.

Four or more.

I'm not sure if these work, but I have 4 Amiga computers. Three A500s, and one A3000.

Two Win XP laptops, one linux desktop, and one Vista Home premium desktop.
