Hello I've been debating on either getting the 15 or 17 I love to play games, make some videos now an then work on garage band. I also like to do normal things like surf the web, email, and just play some tunes. I'm a freshman in college and I might want to be a CS major but not sure if the computer will affect this. Also is the 17 really much better than the 15. Also as for the express card slot on the 17 I like to take photos to and import them but how will I without an SD slot. Do I have to buy an adapter for the USB or a there faster adapters for the other slots? Thanks really appreciate it.
