All of the Atom models will perform basically the same. I have used the 500t, 700t, ASUS 810 and the Envy x2. The WEI was 3.2 on the Atom units and I found the ASUS to have the best inking experience (Wacom). The 700t inks more fluidly due to the larger processor and 4GB of Ram. The ASUS has about 16 hours of battery life at a high screen brightness which is much longer than the rest. They are all riddled with minimal storage, but if this will be a second machine and not your main computer you should be ok. Not all of them have NFC and the Envy doesn't have a stylus available yet. I would get the Dell before the TP2, but the ASUS is the best option for the price.
