so you know what you want it for.....

anything can store data, ebooks, music etc. and most of them can code, write and calculate extremly complex math problem, you just need the right program for it.

just buy anything off the shelf.

reading your question and other's reply and your reply, i could make out the following......
1) you know you want a computer
2) its got to be a laptop
3) you want a brand name

what is confusing is......
do you want to show it off or you just want to get work done?

these are two different things

make up your mind on that...
