New iPad after 6 months or whatever it is? Really? Apple... Just LOL.
As for computers... if you LIKE computers, and love messing with them for the joy of it, buy a PC... much more customisable and upgradeable. If you don't like computers, and just want to get stuff done, buy a Mac. Simple as that really. You pay through the nose for what you get though.
Personally, I like the choices offered by building your own PC, and the price performance ration goes through the roof.
I game on my computer too, so Macs are just a no go area for me... ancient and limited GPU choices etc... major pain in the ass to overclock etc... and you can't build your own (not easily... or legally anyway).
