I love the term 'gadget lust'.

I think it applies to me for sure.
I have an IPad and a Kindle and both bought within a month or so of each other.
For weeks I considered getting either/or. I had lusted after a Kindle for a year or more but I also loved the idea of the IPad. I finally settled on the IPad. My reasoning was that, if I bought a Kindle, I would still lust after the IPad because it was so much more versatile. I just didn't consider that it could also work the other way around.
I was/am very happy with the IPad. It is everything it says and a bit more but darn it, I still wanted the Kindle. It is also a very good time to buy as the Aussie $ is so close to the US$ - there are always justifications in my mind if I want something badly enough.
So, I am the smug and happy owner of two wonderful gadgets that I didn't own six months ago.
