Re: What to do, what to do?
Only some editions have a downgrade licence.
It can be difficult to find drivers.
I think this will benefit OS X, Android, GNU-Linux (Such as Redhat, Centos, Debian, Mint, Ubuntu). Migration from XP will be even slower. Over 40% of PC users still use XP.
If you are using a high end Laptop or Desktop bought since 2002 the need to upgrade (other than for gaming) is hardly compelling compared to 1992 to 2002. Especially for business. This is part of the reason for big growth of Tablets vs Laptops/Desktops. People are getting a Tablet and KEEPING their older PC.
I have done support for Vista & Win7. MS has progressively been losing the plot on OS development since NT3.51. I blame the success of Win95.
Windows 7 is nothing more than what Vista should have been and ought to have been free to every Vista user. A lot of machines sold with Vista are now running XP or Win7.
Windows 8 looks like a genuinely new version of Windows. Maybe by Win 10 it may be sensible, but it looks like MS has been seduced by the iPad. They need to notice that Mac Air doesn't run same GUI or version of OS as iPad and iPhone.
With WinCE / Winmobe they made the mistake of copying the Desktop GUI. Now they are making the mistake in opposite direction. Really you need 4 to 6 OS versions and DON'T give them the same name. Or at least 4 GUIs:
1) Small to Medium Phones
2) Very large phones to tablets
3) Regular sized stuff with keyboard and mouse and mostly used for content creation
5) Embedded Devices such as Routers that have only a remote Web/HTML gui
6) TVs & Setboxes with only a simple remote control.
Strangely GNU-Linux can do all of these. Possibly because historically it was worst at (3). Today there is nothing wrong with GNU-Linux desktop, except possibly for Ubuntu Unity. But unlike Win8 on Ubuntu you can easily swap the desktop to one of choice. Curiously MS once had this to extent on NT4.0 you could have Program Manager and File Manager instead of Explorer. Replacing Explorer's File Browser Window with File Manager would have been nice, though really the solution is to open two Explorer Windows.
However File copying & Moving in Windows is still rubbish and unreliable for large amounts of files and where some files have various attributes compared to xcopy and other CLI tools.
