I'd like to see more pushing the envelope of what HTML applications on mobile devices are capable of. Currently devices use the Facebook, Mobile and YouTube mobile sites. These don't make great use of HTML APIs. There is little in the way of offline support for example.
I'd like to see developers, or Mozilla, provide versions of these applications that are equivalent to native. I don't think there is much missing in the web platform to make this difficult.

Native apps + browser, best of both worlds.
The original iPhone had 128MB RAM.
Also opera/opera-mini offers much better performance on mobile than mobile firefox,and opera mini is very light on ram(maybe 30MB-40MB). So while i haven't tried, i wouldn't be surprised to learn that running opera mini on a 256MB android offers better performance than FirefoxOS.
They've made a sensible strategic choice to target a low-end market -- probably the place where firefox-os has the best chance of competing with Android. Trying to have a high-end flagship would dilute their branding and divert their dev efforts.
Developers use high end phones.
it may be in the interest of firefox-os to compete with the low-end market for the time being, where expectations are low, while polishing the OS for release on a high-end phone when high-end features are thought out.
