What about mobile webApp development?

Well, of course we must talk about Apple here. The iPhone revolucionized the mobile phone world, and was the firstsmartphone with a real browser which everyone could use. The iPad was the first succesfull tablet device, and their additions to safari, even when they could be considered the "browser wars" of the XXI century, are really useful and powerful for web developers.
When the first iPhone came, there was no SDK for it. WebApps would be the iPhone apps, but at that moment it was not enough. Even forgetting the limitations of the original iPhone, there were many thing that couln't be done in a web browser... or could they?
When the SDK came, everyone started developing for it and forgot the webApps, but safari has continued improving. Now, webApps can be stored and used offline, with the hardware acceleration for the CSS transforms you can attach fast and interesting visual effects. WebApps can store data locally, access the GPS device, the accelerometers, etc. WebApp developing for mobile devices is getting more interesting every day, again.

And... which other big benefit does it have? in my opinion, two big ones:

• Availability. Everyone can use your webApp now, you don't have to submit it to an AppStore, it doesn't have to be approved, people don't have to download and install it. When they find it, it's already there, ready to use. This includes automatic updates too :-)
• Availability. Yes, it's the same as the first one. Your app will be availabe for everyone, independent of the device they have. They have an iPhone? the app will be there. They have an iPad? the app will be there. They have an Android phone? the app will be there. They don't have any smartphone or tablet but have a computer with a web browser? you already know the answer.

Of course, always keep in mind your possibilities and limitations. an FPS shooter would be too slow (today) as a webApp, but many other things implemented as a webApp can be just like native apps, or even better (you can access always the same data from every device or computer you like).
