Hey, thanks for the replies everyone!
I wouldn't worry about the "No Computers" thing. They have electricity and DJs so there must be computers. How else would Vinyl Scratch lay such awesome beats on the dance floor?
Hmmm. I have seen 12-episodes of MLP:FIM so far, and apparently the episode with Vinyl Scratch wasn't one of them, so until I read this I wasn't aware of that character or that the ponies had electricity. Everything that I have seen so far in the show has been open-flame lanterns, horse-drawn ploughs, quill pens, and using dragon-breath to some how magically send letters. However, if there are DJ ponies out there with turntables, that means that there are transistors out there (or at the very least
"firebottles"), and I can work with that!
How can the ponies have comps, electricity, etc.? How are they going to be able to run and use things without fingers/hands? All they have is hooves. 
Hooves are yet another reason (among many) as to why you will never ever in a million years see me joining Liedt's Ungulates United local #416. (Another is the fact that my favorite kind of ungulate happens to be square-shaped, has five holes punched through it, is steam-grilled on a bed of onions, and comes in a white paper sack that says "White Castle" on it!

) I replied to this topic about a MLP cutie mark just for fun-- I tend to use a couple different vulpine characters of mine as my fursonas in the furry fandom at large-- I am as of yet still successfully resisting the virulent epidemic-like trend of becoming a "brony!" (Either that or I am just still in denial about it!)
Magic.
No, really.
Unicorns can manipulate things with magic, and the earth ponies are innovative enough that they could probably come up with stuff to harness electricity. (Potato battery, anyone?)
Speaking of being really nerdy, I looked up that a potato, when used as a battery, can produce about 0.00027-watts of power (by the way, it is the potential difference of the copper and zinc electrodes that produce the electric current-- the potato just provides the electrolyte in the form of phosphoric acid). I am not sure how much power my Core 2 Quad-based machine is currently pulling under an average load (I don't have a "Kill-a-watt" meter to check), but to be able to provide enough power for its power supply's maximum rated 500-watts I would need a minimum of 1,851,852-potato batteries linked up in series, and that wouldn't guarantee how long those potato-batteries could provide that amount of power. Despite my looking, I could not find a listing for the amp-hour rating of a potato battery!

Hmmm, while they wouldn't be as good to use as a battery electrolyte as lemons, apples contain malic acid. If I could find enough copper and zinc (or even better copper and magnesium) to use as electrodes I could probably wire-up my PC to 1.85-million apples in the trees of Applejack's apple orchards to use for power! You don't think that she would mind, do you?

Otherwise I had better use my pony hooves to start scratching at the ground to find some healthy chunks of Uranium!

The pegasus ponies have shown to control the weather, so lightning could be a startup...boost.
Lightning may be great for time-traveling DeLoreans, but when it comes to computers lightning is a Bad Thing. Despite my having all of my equipment at home wired up though decent surge protectors, over the years I have still lost a router, a wireless access point, and most tragically a
SGI Indy workstation to lightning storms.

Those weather pegasi are not getting anywhere near my underground computer-laden cave!
