I'll chime in here to my 2 cents...
It would be a good idea to pay attention to the music he listens to, as someone up the page said, since he might want to lean more toward an electric;  if his music taste runs toward heavier teenage music, he might be more keen to learn on an electric and keep learning.  My first guitar was an electric back in the day, and I don't think I suffered because of it (it was a Univox Les Paul copy, with the bridge pick-up missing--at $35, it was the cheapest guitar in the pawn shop, which is why I bought it those many years ago 

 ).  The key is retaining interest, and playing songs you know helps (in addition to the 'show off' value of playing for yer mates).
I also highly highly highly recommend the Guitar Handbook by Ralph Denyer, 
The Link .  It really helps in understanding music theory, etc, in a way that is useful for the beginner, but even after 20 odd years of playing, I still find it a handy reference.  It covers everything from basic chords, to fancy pants modulation stuff, to how to repair or build a guitar.
I was always a Telecaster guy, and Fender's range of Squire guitars are fine for a beginner.  Epiphone makes nice electrics in the lower range.  Places like the Guitar Center usually sell nice package deals around Christmas, with a guitar, amp, soft case, etc.  I would, however, very highly recommend Texas Music Emporium ('The Music Store That Ate My Brain'), although I admit I haven't been there for years, but in the past it was a great store, locally owned.
Current guitar is something called a Fleetwood that I bought in the UK 6 or 7 years ago, a mass produced version of an acoustic built by a luthier in West Sussex, kind of like a standard Takamine;  has nice mother of pearl inlays, a built in pickup, equalizer, etc.  Nicest guitar I ever had, and has been pretty well wearing: moved from England to Ireland to the US and back to England again.  Never saw one anywhere outside of the shop I bought it...Fleetwood guitars ring a bell with anyone?
