I can only speak for myself why I do not get a tablet, nor do I plan to:

1. My android smartphone does whatever I need to do for business
2. If I need something of the size of a tablet, I bring my 10" notebook computer along and if WiFi is not available, I use one of the many free apps to tether it
3. Tablets require a case. My notebook comes with a lid and a standard keyboard [though I still use a case when traveling]
4. And finally [and this is critical to why I have an android smartphone in the first place] if you want a traditional keyboard, you have to pay extra. And then what do you have? A notebook computer.

So why did I bother going android? More like I left Blackberry. I had a Storm, then a Storm 2, but I was waiting for the Torch with its slide-out keyboard to unhook from AT&T and become available on Verizon. Needless to say I was disappointed when the Verizon version came only with a touch-screen. Bye-bye Blackberry. So which android phone did I get? I'll give you a hint. It is only phone in Jason Hiner's top 10 that had a slide-out keyboard.
