There you go. I've been touting the 11" MBA as the ultimate iPad killer but of course when you're in an iPad fanboy zone... you're wrong.
Next, sell that iMac and just get a nice external monitor for that MBA11. They're big and cheap these days.
Personally, I can't think of any reason for an iPad myself (even though I have one). Yes, it has data capabilities (and the MBA doesn't) but I can use my iPhone for connectivity to the outside world when needed.
I love my iMac and its power. Would never sell it
I don't like the mess when you constantly use a laptop and then connect it to a Monitor. The windows lose their position, have to be resized all the time...I hate that.
