I am not a big gadget fan. However, I do have a salad spinner. I love my salad spinner. I eat salad just so I can pull out the salad spinner.
It is mesmerizing to watch the salad whirl around. And then, to see the water that comes off of it - and to see the color of the water. Ugh. Try it sometime with bagged salad. That prewashed stuff has a lot of dirt on it. I no longer buy salads in the bags.
My salad spinner came with a berry bowl that is great for gently spinning the water off berries.
So why would you need a salad spinner?
It makes your lettuce so much crisper. You know how you eat salad out at a restaurant and you wonder why your salads don't taste like that at home? It's the spinner. Dry lettuce is crisp lettuce.
You can use a clean pillowcase with the same effect. Just make sure to do this outside.
