'The technology research and advisory firm Gartner released a report on Thursday, forecasting that by 2017 shipments of devices employing Google’s (NASDAQ:GOOG) Android operating system will hugely surpass shipments of Microsoft Windows PCs and phones. Shipments of Apple (NASDAQ:AAPL) iPhones and iPads will be nearly equal with products powered by Microsoft. Henry Blodget at Yahoo Finance remarked that “Microsoft could be completely irrelevant in three or four years if they can’t make headway in the smartphone or tablet market, where they’ve been struggling.” '
Since you mention it, I guess I'm one who thinks of Android and iOS as beginning the Death of the PC. But Vista was definitely an early sign that all was not well with Microsoft. Even then I expected Linux would supplant Windows, but didn't yet know by what route.
Android is an operating system for the mobile web.
Mobile web applications don't likely run on the computer but mostly run on a website. Mobile web applications largely require a wireless connection to a website. File storage is mostly on a website or transfer to a desktop computer.
And otherwise, look for the quad-core Atom processor to be a blockbuster for tablet computers. That processor will run Android but more likely will run full-Windows. Then file storage can be on the computer and applications like Photoshop Elements can be run.
In fact, the desktop computer can be for file storage even for those who otherwise don't know what a desktop computer is for. That's a desktop computer for file storage instead of paying $50 a month for file storage that requires laborious upload and download.
