It seems like a sure-fire way to encourage quick generation of new applications for the next S60 models. There are a couple of interesting issues though. First, given the inherent insecurity of most browser based applications, will the Web Run-Time create security issues for the S60 phones? Second, the apps are installed unsigned. This would seem to eliminate the possibility for those with restrictive mobile phone service providers from participating in the presumed burst of S60 applications. Finally, how will all those owners of current generation S60 phones feel about seeing cool new web applets appear that they can’t use?
That said, I’m looking forward to seeing the S60 3rd Edition Feature Pack 2 based phones appear with Web Run-Time. It might give Windows Mobile 6 and even the Apple iPhone a run for the money.
