So.. My opinion.. Just for the record.
Topaz Studio on an iPad or similar tablet might be a nice toy to have, but Topaz is not priced for the "take family photos with my phone" crowd.
As far as "the cloud is where the industry is going"? No. Not really. Not for anything serious.
The new Lightroom CC (which I will never use) is merely Adobe trying again to hone in on the phone crowd, trying to make a slightly upgraded (paid) photo editing for the crowd that might otherwise use Google and Picasa or similar. Adobe really, really wants their money, because that is where the bulk of the billions of simpler photos are being taken.
A customer base of merely "real photographers", or "the millions of slightly serious people making snapshots". Which one to make a business case on. (One problem with pure snapshot users is that they are used to "free"..
There is no money in "free", unless it pushes a customer towards a high chance for an up-sell. )
Think Topaz Studio. (Free to download/use with the basic adjustments, but really just a marketing vehicle to sell the paid adjustments.) That is how it works these days.
The new simplistic Lightroom CC is merely Adobe's desktop compliment to the already existing "Lightroom CC" for Android and iPad. They then unfortunately renamed the original Lightroom CC to "Classic", which was a serious mistake and ticked off professionals. ("Classic" gives the impression of "no longer made/maintained, on its way out in a year or 2, was great once". Think "Classic car".)
But for any professional photographer, Lightroom CC (new cloud based) is utterly useless.
Coming home from a session/travel/hike, my most-used camera without even thinking of swapping memory cards holds 96 GB. Each photo at 40-50 MB, and with bracketing spewing out 3-5 of those image files on each button click, it can fill up rather easy.
Since the cloud based Lightroom WILL import to cloud, and in fact by their FAQ stops if your current cloud account runs full, to import that session would then require up to 96 GB in the cloud. PER import. Apart from all the upload wait times on slow upload speeds and limited small-town networks. (Add waiting time to import while you buy a larger cloud allowance from Adobe. )
Adobe simply cannot sell large enough cloud configs for large session photographers. Which of course is their real purpose, since their Cloud space is VERY expensive compared to others. Nor can Verizon/AT&T sell large enough Internet data plans to support travelers using such Cloud solutions. (Verizon stopped selling their last truly unlimited data/speed Internet plan back in 2011 because of it's abuse. About the same time Microsoft dropped "Unlimited storage" for their OneDrive accounts.)
Cloud-based Lightroom also cannot work with add-ons like Studio and others. Think about it.. It would require that massive image file to be downloaded from the cloud to your local system, and then after editing uploading the edited image again. Single images at 35-50 MB, HDR and panorama files MUCH larger flying each way on each call to an external editor. Every operation would be at a crawl. Off to get coffee and watch the news while exiting Topaz Studio or other external editing software.
Lightroom CC (any cloud based software) will also be a serious problem for anyone traveling a lot.
For example, ALL my Internet needs are handled by carrying multiple Wireless Mifi devices along (both Verizon and AT&T plans), managed/hidden by my router.
So no ultra-fast fibre-optic uploads, only whatever capacity remote, small-town America has on their wireless towers, which makes for slow upload speeds, dependence on who is streaming video nearby, and a limited and expensive data-bucket every month..
So for Lightroom, I will stick to Classic (until they throw that out, loosing all serious photographers in the process).
As for other Cloud based photo solutions in general. They are toys for the single-image, family photo crowd, whose photos from phone and tablets already automatically sync to various cloud systems (Google, OneDrive, DropBox, ...).
Since only on-device (on phone/tablet) Unlimited data plans exist today. NO wireless plans in the US today offer unlimited tethering (connections for computers, TVs, Roku, ...)
Cloud based imports can potentially be used by the photographer/artist who only take single or a few artistic photos.
But don't even think of Wedding, Travel, or similar types, who come home with 500-600-800 photos that must be quickly culled and cut after importing them.
