Microsoft's Bill Gates and Steve Ballmer are already talking about the Windows 7 operating system (OS), Vista's successor, which won't launch for at least another two years. A technology columnist for 'The Wall Street Journal' would like to suggest that Microsoft's family of Windows 7 products share the same stock keeping unit (SKU), instead of a different SKU in every updated edition as was done with Vista. A higher resolution screen contains more pixels than lower resolutions, rendering the icons smaller and harder to read. A 'smart graphics system' for Windows 7 could draw an icon the same size as a lower resolution screen, and use the extra pixels for a 'crisper, more detailed image.' In addition, Windows users could fully utilize the market's new ultrahigh-resolution LCD displays. Like Apple, VMWare and Sun Microsystems, Microsoft's Windows 7 file management system should be as easy to use as a Word document file system, and the OS should be capable of taking 'snapshots' of its own condition. The OS should be capable of being restored to its previous condition, even though it might require huge amounts of disk space. However, the prices of terabyte drives are steadily decreasing. It would be possible for Windows 7 to be proprietary, for-profit, copy-protected, and open to user control and inspection all at the same time. If it's true that too many cooks spoil the soup and large teams of programmers are too bureaucratic to be creative, then 'Microsoft is big enough to spend whatever it takes to build a team smaller than everyone else's.'
