I'm still a beginner, and went through the same decisions over the last year or so; I now have both. What I experienced (I play only at home, for myself) ...
Electric advantages: easier to play, easier (but not easy) on fingers, lots of sounds
Electric disadvantages: you need an amp, you need a cable, you'll end up wanting a pedal or 2 to play with the tone, electric seems to generate more GAS
Acoustic advantages: you can take it anywhere and play, no electrics needed
Acoustic disadvantages: harder to play (relatively), more painful on fingers but you get your calluses within a couple of weeks.
Whichever one you get, you'll be wanting the other type soon. Make sure you have the shop include a setup, tuning and intonation check when you buy.
I started with a Yamaha Pacifica electric, very nice Strat type but hard to find in stores. The Squier's are nice and have a good range of prices. You can probably get a good deal or package involving a Squier. For acoustic, I'd look at a Taylor Baby, Big Baby or GS Mini.
