I have the tablet 4 u
I use the Lenovo Thinkpad Tablet. It is a very nice tablet, I take notes with it all the time (tho I am not a journalist). I really like the ability to write on the tablet, my only issue was with the screen protector. When writing I could tell I was writing on glass and not paper, there was no drag so it just felt difficult. I picked up a new screen protector (armorsuit) and it works great. Has fantastic drag, and it is very nice.
You should be able to pick one of these up for around $400. I bought mine off ebay for $219 used with a dock and the pen. If you would like you may contact me at email@example.com I have a few people from these forums emailing me with questions about tablets and my experiences. I would be glad to help if I can.
Best of luck!
