I'm Dan Ackerman and this is CNET's Laptop Buying Guide.
I'm gonna start you off with three quick tips.
Number one, don't buy too much laptop.
You used to have to spend $1,000 in order to get something decent.
These days, $600 to $800 should get you a Core i5 CPU Windows 8 and a touchscreen-- that's pretty much all you need.
Number two, think about travelling light.
Anything bigger than the 13-inch laptop is gonna be hard to carry around in multiple days per week.
Think smaller, your shoulders will thank you.
And number three, design is [unk].
A lot of these systems have the same components inside, so don't be afraid to pick something just based on how you like the look.
After all, you've got to carry it around to the coffee shop.
All your other questions should be answered in our buying guide below, but those quick tips should get you started.
