As someone who started with both acoustic and electric guitars... you should make the choice based on what kind of music you intend to learn and play.
If you want to stick to acoustic songs or just strumming chords in the hallways of your high school so that vegan chicks will latch on to you, get an acoustic. If you want to perpetually compensate for everything in your life while putting on a thin facade of confidence, get an electric, learn the major and blues scales. Either way, you'll just be chipping away at the time it takes to learn how to solo over everything to the point where the actual melody of the song is lost in a sea of uncoordinated noodling at high speeds (that is, if you want to be the best guitarist ever)
Make sure you get the biggest amp in the shop too. Doesn't matter what wattage you have on it, or if it's been used, or if it's a tube amp or whatever. Just has to be big. You'll need it for when you practice in small rooms with your band so that you can laugh at how appropriately sized everyone elses equipment is.
Okay, now that you have all that down, you need to start drinking heavily, or doing an excess of drugs. You should also begin working on trying to be more pretentious. If someone says something about the guitar, you must correct them.
IE
"My guitar has strings on it"
"Uh, Actually, no. Your guitar has thin outstretched metal lines on it that make noises. I like to call them noiselines"
Try your best to give a small chuckle after someone else plays something, or say something like "Oh, Led Zeppelin, how quaint"
Okay, you're now fast on your way to becoming a truly masterful guitarist. Your band should be struggling to get you to play actual songs instead of 4 minute solos, and your kidneys should be failing. This should aid in maintaining an exquisitely greasy appearance. Stop shaving, bathing, brushing your teeth etc.
Focus more on sweating profusely, growing back and shoulder hair, building up plaque and so forth.
And last but not least, you should make a failed attempt at a solo album where your singing devolves into talking half way through each song but you keep going anyway. Write most of your songs about girls that don't exist. Make sure it gets almost no attention, but still way more than it deserves.
But seriously though, either choice is good for a beginner. I just think the electric is more versatile.
