And that is why it has neither. At $200, you can't include throwaway features that don't appeal to a majority of your target market. For myself, I don't know why I'd care that my tablet was a phone. I already have a phone; if I want to put the tablet on the internet I tether it to the phone.
The problem is you will always want to put the tablet on the internet, because it is useless without it. It is an extra burden to take your phone out and turn tethering on everytime you want to pick up your tablet.
On the other hand, why pay for a 3G plan for every device when you pay for just one and share the connection? Extra batteries are cheap compared to 3G data plans.
