Help me find my laptop (wife must approve)

I live in a city where there are limited outlets for electronics. Mostly just Best Buy and Staples. I need to begin planning to replace this POS that I'm currently typing on. DVD/CD Drive is a must and I'll need a decent amount of storage.

Everywhere I look it's all Windows 8 and from what I understand; they are best used with a touchscreen. I went to BB and didn't really notice huge differences between anything really. I am wondering for your guys opinions? Point me in the right direction.

Need:

DVD/CD drive, enough power to stream most media (I cut the cord long ago), storage would be nice...at least 500 GB's, and I'm leaning toward touchscreen unless someone knows of a reason not to go with one.

Thanks in advance!
