For me it was just the opposite. Having owned an iPhone 3G and 3GS, I was completely nonplussed by the iPad announcement. I couldn't at all see how it would / could fit into my life.
However, with the delay of the international launch, I had the luxury (!?) of getting to see new owners in the US responding to the device, which I have to say has been as close to a unanimous positive experience as I've seen a gadget generate.
Then I started to realize just how much I would use my iPhone to couch surf, even when there was a laptop handy. That, the e-books capability, and the digital photo-frame capability was enough to get me to dip my finger in the lake and I put in my pre-order for the 64GB 3G model about a week after the pre-order season began. Of course, my irrepressible gadget-a-holic-ism had nothing, I repeat ... nothing, to do with this decision.
I'm scheduled for the June 7th delivery wave. Until then, I satiate my curiosity by coming to places like this and vicariously "owning" an iPad through folks like you! Just watch it who you're calling "ripe", ok???
