This week at CES the T470 will be announced. So if you're thinking about buying one you might want to wait for that
If something goes wrong, you'll have a long wait for service, due to unavailability of parts or replacement systems. I had to wait literally months for "next business day" service. (Under normal circumstances, they really do show up on the next business day.)
Wait a few months, let any teething issues shake themselves out, and then get one. If you can't wait that long and need a new laptop now, grab an established model.
