So, whilst I like not having to constantly fend off virus attacks I find myself on the point of junking Linux on my dual boot laptop and returning to the Windows 7 fold.
This mirrors the experience of most non-geek attempted converts to Linux, and illustrates some of the reasons why the OS has never made a dent in the desktop market.
Besides, anything that could faithfully emulate the Windows environment would also be vulnerable to Windows viruses, so if you need to run applications that are available only for Windows, then actually running Windows itself is the obvious solution.
