There is always the problem with those that can't afford to upgrade, it is sad but, not wanting to sound harsh, life still moves on. My In-Laws had an email recently from their bank saying that their online banking service will no longer support systems running Windows XP. I can see both sides with Windows XP no longer supported there will be no security updates, something of concern for the bank. On the other hand, my in-laws have a computer that will still deal with emails, let them spruce up their photos, write and print the odd document, which is about all they do other than on line banking. Of course they could upgrade to Windows 7 but support for that will be withdrawn in the foreseeable future so it would have to be Windows 10. There is not only cost involved, my father in law is 86 and I know he will struggle to use Windows 10 but it is another case of life moving on.
There is also the point that Poser 11 will be a high cost for some who have a very restricted budget if they are still using 32bit computing as, even if Bondware gave them a free copy they would still have to spend on a new computer. It certainly is not a nice place to be in but Bondware is clearly looking to support only one version of Poser, hence scrapping the Pro version, how long before they stop worrying about making sure Poser 4 and five content still works.
