My current XPS 15 is almost 4 years old... so definitely looking for a replacement. I've had problems with the keyboard, but not the ones you mention. A few keys have fallen off, but a bit of super-glue have seemed to do the trick. I did run into other problems with the keyboard (some keys would not depress), but I took apart the entire system, removed the keyboard and cleaned it off with an airgun, which solved the problem. Basically food and other gunk got caught between the keys. Not a perfect product, but given how much I use it, not totally unreasonable either.
