Kev and I use the writing space for our unsorted mail and as extra prep space. The built-in counter original to the house probably measures a total of four feet. One foot is consumed by our petite microwave, and more precious inches are used up by the ever-present toaster (I need my poptarts!) and our knife block.
That's why I want something like this from IKEA:

Or this:

They offer a greater sense of permance (although the library desk is quaint and I do love it) and much more storage than just a simple work top. I'm not crazy about the natural wood color but hey, maybe if I ever get around to refinishing the kitchen table, I can stain one of these as well.
It's not likely that we'll be dropping $330 or $500 on additional kitchen storage, but a girl can dream, right?
