My graphing calculator is The Calculatrix. It’s not a name I tell to my friends often, though.
My old car was “Baby.”
The new one is “Rhapsody” (it’s blue). But I usually just call it “Baby” too.
If I gave my favourite stuff names, I’d get th’ names all mixed up, and — well, I don’t know exactly what would happen next, but I’m sure it wouldn’t be pleasant.
So … no. 
My first car was Bertha, and the car I had two cars ago was Digby, but this car, a Kia Rio, is merely El Kiario, which I don’t think entirely counts.
I’m so busy conjugating new endearments and nicknames for the cat I don’t have time to name other things, other than the “Mr.” (never “Ms.,” interestingly enough) terms when in mid search, or mid tantrum.
My sewing machine is named Pfredd.
It is, of course, a Pfaff.
My wife did once, but it wasn’t really my fault-I had to work late that night and I just too tired.
My cars have been named:[ul]
[li]Big Blue[/li][li]Little Green (a VW beetle)[/li][li]Lance Voyager (my California minivan)[/li][li]Grace (my white Southern car)[/li][/ul]
My house is named Dogwood Manor.
Monica - “here booky, booky, booky” - rofl!
I had a horribly designed Datsun F10 (voted one of the ugliest cars ever, and so underpowered it tapped out on a hill in San Francisco) that I called the Moon Buggy
My now-wife-then-gf had a Mitsubishi Gallant we named Lance - there was something about that Camry-wannabee boredom-mobile being named Lance Gallant that made us chuckle.
I name some of my guitars, although right now I have the few guitars that I will have for a long long time and I tend to refer to them by their make, but with emphasis - not just a strat, but The Strat. I gotta name that guitar…
My cars name is Eugene. And when Eugene needed a new set of tires I told my wife that I needed about $500 to buy Eugene some new slippers. She thinks I went nuts.
I typically reserve nicknames for the living, but we couldn’t resist naming the telephone ‘Phoney McRing-ring’.
Yola - I loved the ‘cousin art’! That’s it! That’s what it has been trying to tell me to call it!
Come to think of it, yup, that’s what happened. They told me. Little sneaky things tricked me into thinking I gave them names. Must have a talk with them. 
My 5-pound sledge hammer is called “The Persuader”.
When I was around 13-14, I walked to school. Every day I’d pass this one house that had a lawn jockey, and every morning I’d say “Good Morning, Harry”. The rude bastard never once answered back.
Let’s see, my old black POS Dodge pickup was known as Boris. Our current Subabru Outback is known as the Mewbaru after the plush Mewtwo pokemon haning from the mirror. Our coimputers are known as **Snazzy, Rookie, Little Blue, ArtGeek **and Horken. (Only the working and activve computers have names, the ones with their guts strewn about don’t have names. Except for Horken, he’s in retirement. And the server is unamed as well.
My first car was the “Blue Falcon” - '76 Chevy Nova. Loved that car, even after it kissed a tree…
Teddy bears and stuffed animals also get names - it’s the whole anthropomorphism thing.
Bwahaha!! Mascot and President of the phone company!
[sub]ahem, anyway…[/sub]
I also don’t usually name inanimate objects, but the violin I recently bought bears a tag inside with the name “Clayton Hurst”. In conversations with the luthier I kept saying Randolph Hearst, so the violin earned the nickname “Rosebud.” (what else?)
I’m spreading word around, so when I’m on my deathbed, asking for it, people will know not to toss it into a damn furnace.
I don’t give anything a name if it won’t answer to it. My house is called my house. My car is called my car. My computer is called my computer. My cat is called my cat.
Inanimate? Should I be insulted? Or should I just start looking for the hidden camera?
My ex-car was called “Lightning”.
('Twas anything but!)
My car’s name is Sasha. I’m thinking of naming my mtn bike, but I can’t think of anything good. It’s a dark green men’s bike. Bobby comes to mind, but I hate that name.
p.s. I’m a little tipsy. Happy new years! hahaha!
I don’t name inanimate objects. When I recently bought my first guitar, I gave him a name, but I rarely use it. I’m just not one to anthropomorphize the non-living.
