Not nearly enough...
Only three, currently.
My main desktop is a 2009 mini server. My wife has an iPad 2. Baby girl has her very own iPod Touch (2nd gen, so major hand-me-down - she IS <2 years old btw).
"Others:"
Two 'droids
- both of us have Android phones - a Nexus 4 and a Moto G. I'm almost certainly switching
back to an iPhone whenever the 6 lands
if it does indeed have the larger screen. Anything smaller than my Nexus 4 feels like a toy (my opinion, of course, and the main reason I left the fold...)
Three Windows machines
- an ancient Dell GX620 that currently serves as a HTPC (but a replacement is on its way; will run Linux. When I finally replace my mini server, it'll move to this duty)
- Two quite old Dell laptops; a D820 running Windows 7 (wifey's personal) and a D520 running XP (I use it for work) - they both work great with their SSDs and 3GB of RAM; can't justify replacing the old geezers! But when either of them DOES die off... wifey gets a Macbook Air and I get... whichever Dell isn't dead lol.
- And a PS3. I, too, don't have much time for gaming nowadays, since my tiny princess entered this world.
