hey, bite the bullet and go for a tablet - it's like a laptop except you can write on it with your own handwriting.
I've been using my HP TC1100 tablet laptop for a year and a half now, its great. The processor is fast enough, it can connect to wireless devices and to bluetooth device. It's light, very portable and quite sturdy too... I've dropped more than once.
It costs around £1k so it's not the cheapest, but it is the future and its so nice to read your laptop like you would an A4 pad or magazine.
