Should i sell my laptop to buy samsung galaxy note?

galaxy file is like everything i involve and it's portable, i can carry everywhere, since i have the Internet in phone, i can of late put it in and it will work great. it costs approximately about $700 dollars, i cannot wait it comes to us carriers. My laptop is just overly big and heavy to carry around and the battery is only last for a hardly a hours, the galaxy note last longest and i will buy the new trent battery extender for it, extra 50 hours, that's great. i'm having a hard time deciding what should i do. Should i supply it or not? i mean i just use the internet in my laptop, same as my current phone, but smaller screen.
