Q: "That doesn't either."

A meaningless question. Slow relative to what? Slow for whom? What sort of app are we talking about?

No, it doesn't answer the question, it suggests more questions to ask to make an informed answer. It's just a short cautionary tale to make the user consider what type of app he/she is building, and to consider if significant activity within the app is, or not, likely part of the GC/JavaScript (or HTML/CSS) that would suffer in some cases vs local, native, code.
Personally, I tend to agree with the original article that GC is an expensive thing to put in most apps. BUT, you need to be pragmatic about determining if the additional margin of execution speed from not having a GC justifies the coding effort.

#6Hacker news webapp for mobile - http://hn.premii.com
I wrote this client. It is as fast as most other native HN mobile apps, but mine works on iOS, Android browser, and windows phone 8. It also works on regular browsers.
I have wrapped this in hybrid app using phonegap, but only submitted to Google play. One day I will submit it to Apple too. https://play.google.com/store/apps/details?id=com.premii.hn
But it is not a simple task to make fast performing HTML5 app that works on all mobile browsers.

Having said that... you're right in that mostly this posting is to fulfill somebody's job requirements, rather than a substantial amount of content :-)

Re: Are mobile web apps slow?
#10Drew's post was very well explained, and relied heavily on concrete examples. This rebuttal was very much the opposite.
