It seems like Adobe Photoshop will be provided only by a subscription base not a package type.
Since the 'Photoshop' is a market dominent programe that wildely used in various industry, so does Microsoft office.
If this Adobe's bold plan goes well, whole software companies, of course including MS, should be re-evaulated.
'Irreplacable' that would be key word for software companies.
Look at carefully.
