I have had mine for just under two years, though I had a Sunbeam stand mixer for years. I will note that I have found some of my baking recipes seem to perform better with the KA's extra power and more diverse speeds for creaming, blending, whipping, and especially kneading.
What I *really* love it for is pureeing and grinding, with attachments. Homemade sausage and ground beef, and processing fruit and tomatoes - it is really great for those things which I would not have tried without it.
Also, creaming butter with some olive oil is great for making spreadable butter which keeps well in the fridge, but didn't work well with my prior mixer.
And it's pretty - not a big reason for having one but a reason to enjoy it more if you do.
There is a book named the "Mixer Bible" which I bought not long ago which has some great ideas, you may want to check into it on Amazon, where I think you'll be able to browse some of its contents. Mentioning this because I don't yet have loads of experience using mine, but having one has me looking for and trying recipes I would not have otherwise tried.
