2 different questions

Hey guys, have 2 different questions which i hope you can help me with.

1) I'v been checking buyer's guide and it says we are in the middle before next update (i KNOW its just based on statistics) - but i'v noticed that some have been talking about an update pretty soon - do you seriously think there will be an update before october? ( i can wait until sep. where the school starts...)

2) I want the 15" with i7 - but i dont know if i should choose glossy or AG - im a student so of course i will move it a little around (not much coz i got a notebook) - but the main workingplace will be as illustrated at the pictures (borrowed a friends HP) - i will typically work with houslight on because i'v got my books and paper besides me - should i go glossy or AG?

thanks
