Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Snow Leopard's 'Keyboard Viewer' Sparks Renewed Speculation Regarding Mac OS X-Based Tablet

Cult of Mac has picked up on the finding and extended the case to make a more complete argument for Snow Leopard as a touchscreen operating system. First, the report notes that in addition to the large Keyboard Viewer window, the option to activate the feature has been moved from the relatively obscure "International" section of System Preferences to the more prominent "Keyboard" section, hinting at movement toward considering the feature an input device.
The Mac OS has long contained a virtual keyboard, but previous versions were half-sized (see below). The old virtual keyboard was clearly not designed for actual typing, and was hidden away in the "International" tab of System Preferences. (Yeah, the keyboard could be enlarged by hitting the green button in the upper left of the folder toolbar, but still, it expanded to only three-quarter size).
The new virtual keyboard in Snow Leopard now lives under "Keyboard" in System Preferences, and is clearly put there as an alternative input method.
The virtual keyboard can be made as big as your screen -- 30-inches wide, if you have a big Cinema Display -- by dragging the window resizer at bottom left.
A multitude of rumors surrounding an Apple tablet launch later this year or early next year have sprung up recently, but little is known about Apple's software plans for the device. While the operating system would presumably be based on existing Apple technologies, sources have yet to come forward confirming whether the tablet will use a Mac OS X-based or iPhone-based operating system.
