Heres a great piece of advice.
SAVE YOUR MONEY AND BUY IT ALL IN ONE SHOT.
Just wait a little while.
Because in the time period, prices can lower and some new pieces of tech can come out.
Come back around about a week or so before buying; it really would be best.
And in the meantime, learn.
Read about tech when you get the chance.
Maybe you won't have to ask us on what you should buy because you'll know everything you need to!
Best of luck my friend.
