What type of laptop to buy?

I'm a Junior in highschool that is looking for a pretty good laptop. I'm willing to spend anywhere from 750 to around 1500. I need the laptop for standard surfing of the Internet, writing papers (so basically having the ability to have multiple tabs open without slow processing. Also needs to be able to run all the Adobe programs such as photoshop, dream weaver, and flash. May also play minecraft PC every once in a while although I know with a laptop it won't run too smooth anyways. Some ideas I had were the new MacBook Air, the new MacBook Pro, and Microsoft's surface pro. If I do end up going for the surface, should I wait until the surface pro 4 comes out? Thanks for spending the time to read this. I'm open to all ideas and suggestions you may have for me.
