GNU+Linux on mobile laggy

Three years on, iphone still dominates the new media smartphone market. Nokia limps along after it's massive head start with Symbian.

GNU+Linux is nowhere near.. too many bugs, too little (if any) QA. GNU+Linux is may never get and succeed in the quality niche.

QA and UI consistency has to be massively improved, will it change? I hope so, but no company has managed it over the last 3 years.
