I cannot understand how come somebody can exchange comfort of developing under flash and nice flashy result of work which looks everywhere exactly the same (whenever it supported) to HTML5 which will be always different on different browser, looks at HTML4, still there is no 100% match in different browser, also everybody has own CSS implementation and javascript total pain in the arss ... c-mon people Flash guarantee it looks and works the same everywhere...
About 10 leading brands - it is Not flash fault that stupid IPad and IPhone cannot display it, it solely Apple fault and responcibility that they cutting their own customers from other technologies!! Apple shame on you! :p
