guitar trainer

which way’s easiest to learn to play guitar?

by book, video, or trainer?
answer only if u know from experience or if a friend knows.
and how much will each cost? i want to learn to play by note, i guess, so i can be versatile like, if i wanna do rock i can, then anything else

this is how i started:
Look on the web and learn to read guitar tabliture,
after you have a basic understanding, start to practice playing simple songs useing the tab. also grab some information on chords, once you have a good understanding in chords the tab comes alot quicker. so thats my advice,
