My understanding is that most freestanding ranges have the controls on the back (where the backsplash is), and all slide-in ranges have the controls on the front since there is no backsplash. At this point, there are only a hand-full of induction ranges out there (free standing or slide-in) so there's not much selection to choose from (as you've probably seen). Between the models, I like the GE Profile induction unit, even though it does have the backsplash with controls.

I've been researching stoves/ranges and am heavily drawn to the slide-in options because they look built in and aren't that much more money. I just think getting rid of that backsplashy thing on the stove is a much nicer, cleaner look. And, I love the idea of eliminating spills between the sides of the stove and counter top. Conversely, though, the other look I love (which is a heckuva lot more money) is the pro range with the over-sized stainless backsplash and high shelf, which is a really integrated look with the fan hood on top. It's just probably much more money than I can justify. I've been thinking a lot about what matters to me most in a range and cleanability at very near the top of that list. I'm tired of cleaning grates, drip pans, burners, stovetops, etc, etc, etc. I find stoves a pain in the bum to clean. For that reason, I'm even considering switching away from gas to a smooth-top. The ones I am seeing don't have that backsplash built-in, either.

I've never had a stove that didn't have a backsplash. I've never had the electronics go out for any reason. It's a stove...aren't they made to stand up to heat?

Most slide in ranges come with a stainless filler piece for the space between the range and the wall so you wouldn't need to purchase a piece of counter for that area.
