Yeah, That is a problem. Apple guys will have to rely on the app store or build the app from source themselves. I'd choose the latter.

Performance issues are more noticeable when you are used to faster tools. I'm not saying that the Stacker News site is not well developed or something like that, I'm just saying that even the most well developed sites and web apps will suffer from performance issues because of browser bloat. People with good newer devices don't notice many issues but people using old weak devices might have a terrible user experience. That's my case and that's why I like small dedicated native tools instead of web apps.
