When Windows 7 launches sometime after the start of 2010, the desktop OS will be Microsoft's most "modular" yet. Having never really been comfortable with the idea of a single, monolithic desktop OS offering, Microsoft has offered multiple desktop OSes in the marketplace ever since the days of Windows NT 3.1, with completely different code bases until they were unified in Windows 2000. Unification isn't necessarily a good thing, however; Windows Vista is a sprawling, complex OS.
I see Mac sales going up soon. I just as well may follow instead of building another OS.
I see the recent investment that I’ve put into learning linux paying off nicely.
