If you are in the market for a new notebook or laptop, the massive variety out there can cause brain freeze. Do you need a business-friendly portable or a big-screen machine with high-def for movies or possibly something in between? Notebooks do overlap a lot especially in size, types and who they think will be using them.
Ask yourself these questions first:1). What will the main purpose of the notebook be?    Business or pleasure?
2). What will you use it for? Movies, creative pursuits, gaming or business
documents and spreadsheets?
3)  What size do you want? Do you want a replacement for your old desktop,
something you can travel with or a good balance between the two?
4). Do you want to use a stylus? A tablet has enough punch for powerpoint
presentations if that is important to you.
5). How tough does it need to be? Are you careful with your things or do you need a
military grade machine?
Thinking about these questions can get you started in the right direction because no one notebook/laptop will do and be everything for you. But you want the one that will meet your needs the best.
