Is there any particular reason why Dell does not support upgrade for this laptop? See: http://support.dell.com/support/topics/global.aspx/support/kcs/document?docid=575111#Inspiron-Laptop
I only bought it last year in July, so it is very disappointing to see that Dell does not support upgrade for it from Windows 7 to Windows 8. I got halfway through the Windows 8 installation, the two things I needed to uninstall it said were "Dell Touchpad" and "Dell Stage" but obviously did not proceed to uninstall those two after seeing the above page.
And I can now answer this myself, upgraded successfully despite Dell not supporting it! Hope this helps others in the future though...
