Yes, you can do some pretty cool cross-browser stuff even today. "Web technologies are catching up in regards to what can be achieved via Android (specifically Chrome) and Apple mobile web browsers." This is assuming native platforms stand still, and they aren't; the web's caught in their cross-fire. Whenever you think something is "done", it's rarely the case. (I know you didn't say that, but it's a related argument people sometimes use in favour of the web.) iOS and Android in a few years could be dealing with home automation, cars, wearables, etc., and while some developers today might say "oh but we just do mobile", in the future that might be like saying "oh we just do 7" tablets". The "catching up argument also assumes web standards are converging, and in the past two years, the increased pace of innovation has made some web technologies diverge. Such as the offline technologies I mentioned in the linked article.
