If I had to choose one or the other — if I had some crazy power but I had to wipe out either native apps or web apps — I’d wipe out native apps. (While somehow excluding browsers, text editors, outliners, web servers, and all those apps we need to make web apps.)

Infrastructure just got even cheaper. Between this and Amazon's EC2/S3, the barrier to entry to getting an app up and running is getting lower and lower.
