Just to add to the evaluation of the increase and where Adobe is going, I'm already on LR Creative Cloud.
Cloud allows automatic exchange of pics between my desktop and iPad. I enjoy this feature but only pay for LR today, not PS. I have 1TB of data for £10 a month.
I used to be on desktop versions and wrestled with hard drives, backups, and the slowness of the desktop version.
The Cloud function is a great addition but how married am I to this solution vs. hard drives? Is it any different than the Desktop only version? I'm merely moving some of the functionality to a newly written app (it is much faster than the desktop version) and I get Cloud backups and mobility.
Adding PS to my subscription increases my cost to £20. Or, for £20 I can get 2TB with LR only. I have to admit the value I'm getting out of LR and if I used PS as well. They can't be free or cheap forever. They require a lot of resources to produce and we'll have to pay for that.
I don't mind paying for a subscription but I am slightly concerned what my library will look like in 5-10 years from a size perspective. 5TB raises my monthly cost to £50 a month. 10TB raises it to £100 a month.
