I had a chat the other day with our IT consultant – he travels a lot between clients and has had his ipad even before available in SA and is of the opinion that a small net book would have worked better for him for off site support as his iphone use and the ipad overlaps so much. He did admit that for me an ipad will be a better option as I want to load drawings and walk around with it.  So I guess it depends on your specific use.
