India, especially, sees people buy these OS-free PCs to install pirated copies of Windows on them, thus defeating the whole purpose for which many people have devoted huge amounts of energy and time.
In India, one needs to have dual boot PCs as certain govt departments deliberately favour microsoft. eg. The passport renewal pdf (from passportindia.gov.in etc)needs acrobat reader for windows as evince, okular and even adobe reader for linux do not work properly to fill the form. I have tried adobe reader 9.5 under ubuntu 14.04 to fill the 3 page application form--after reaching the submit/validate button, the entire application crashes or shuts off. The form/pdf could only be properly filled in acrobat reader 9 under windows7 by me.
Similarly for users of PNB's corporate banking facility online, the webpages are deliberately fixed to use only internet explorer. Using addons like user agent in firefox etc really does not help--and how many linux/ubuntu users in the corporate world would go to so much trouble to just access a website.
Then many cheap and easily available hardware such as webcams or usb wifi devices now coming in the market don't have proper linux/ubuntu modules/drivers and its not easy for laymen to install the modules
I tried to push the use of libreoffice across my organisation but there was too much HIDDEN resistance from users too set in their ways--also TOP MGT not being computer savvy did not understand the advantages of FOSS which would have been a sequel to move the entire organisation to Ubuntu later in the future.
