Ipad is great for browsing the web and reading Ebooks. If that's all you're going to use it for, then thats all you'll need. There are some good games and apps. There is a metric ton of bad apps and games.
If you find you need a keyboard with your ipad, you can always use the $69 bluetooth apple keyboard. I do and it works great.
 
I want to give thanks for everyone sharing their knowledgeable advice, and views. It is very appreciated.

I think for now, the most logical step would be upgrading my phone first. I really like the iphone, or the Samsung s 4g. My upgrade is available in June, so I will have to hold off a little while. Which is good because it will give me some time to think about it more. I rarely need to do anything serious when I'm on the road, or traveling so the other choices might be overkill anyway. I think I will be extremely happy with my new 15", and a nice smart phone to keep it simple. Then I will look at my options again after the phone upgrade. I was looking at the phones today as a matter of fact and they are indeed slick.

Thanks again folks!
