Computers are continuely changing, Moore's law what is it processor speed doubles every 18 months, probably faster now. Not so much what they are going to come up with but what you are using the computer for. Most computers, laps and otherwise have more power then most people even need. kinda of like the ex. of listening to a $4,000 stereo and a $500 most people aren't going to be able to tell the difference. So I would just go pick out something you like and that will meet your needs. You can research forever. I'm sure you don't want to wait 3 years for a laptop. There are a lot of configurations out now so I don't think you'll have trouble deciding on something. Good luck in your search.
I have been wanting to get a laptop, but an employee at MicroCenter said that now wasn't a good time to spend a lot of money on something because computers would be making a big in about three years. Is he right, or crazy?
