Upgrade Path to Windows 7 Based on Upgrade Chart

After Microsoft announced the release schedule of Windows 7, a lot of tech site and bloggers post about the Windows 7 upgrade chart to be ridiculous and confusing like one here and here.

If you see the chart below, the question that rise is “why Windows Vista Basic/Home Premium users can upgrade to Windows 7 Ultimate but not Windows 7 Professional?” others perhaps will ask “why Windows XP can’t be upgraded to Windows 7?” but in the case of Windows XP, I think the answer is because XP and 7 have a very big gap of architecture hence you can’t upgrade it.
