I have $1000, what laptop should I buy?

I'm in the market for a new laptop , and I have $1k to spend it on. What should I buy? I'm looking for a fast, well-built and long lasting machine, A touchscreen would be nice. If I can use it as a tablet, then even better. But they are not necessary, I'll just use it for reading, writing, browsing and watching youtube. But other than that I have no massive expectations from it.
