I have a red 920 that is almost a year old and still going strong. It has been dropped a few times just a couple of marks on the back. I am also running WP 8.1 dev prev and that made it feel like a new phone.
So I can recommend it as its tough but stylish, good enough to run WP 8.1 and with the wireless charging (in car and at home), fully controllable from a Bluetooth headset in the car, solid and reliable etc.etc.
I am deciding now whether to get the new 930 or wait for this supposed new McLaren phone. If I decide to wait it will be no problem as the 920 does everything I need without issues. I'm sure the new quad core chips will run faster but that will not be missed until I actually get one.
Good luck in your purchase choice, sure you will not be disappointed.
