This discussion reminds me ALOT of the Adobe discussion regarding Creative Cloud.
I'm relatively new to Eagle. Been using it for about a year or so and have found it to be a good piece of software. I've tried other solutions out there and am also in the process of reviewing other solutions. (KiCad and Altium... though let's face it, Altium is Windows-only and costs significantly more).
Alot of people are suggesting KiCad as an alternative to Eagle. (Also very similar to the discussion regarding alternatives to Photoshop/Lightroom/etc. re: Adobe discussions). But in the end, I stuck with the Adobe workflow because it works for me and while it does kinda suck to pay a monthly subscription, I also got to use a number of tools from Adobe.
With Autodesk/Eagle, I'm currently subscribing to the $15/month plan to check out Autodesk's changes to Eagle. So far, I like alot of what I see and there are features which I'd like to see work better. One thing that I noticed that I'm getting with the Autodesk version is more PCB real estate. 160 cm^2 is a good chunk of space to work with. That in and of itself is a nice improvement over the Eagle 7 I was using previously.
I can see myself trying out the higher tier for a couple of months to work on a project for something that needs more than 2 layers. So from that perspective, the pricing is very flexible and offers some serious benefits.
Not being able to "buy the software" outright and have a standalone copy to use indefinitely kinda sucks. 😞 While 14 days is a nice amount of time, I can see some situations where if you are working on an isolated machine you don't want connecting to the internet, that can pose issues.
As for KiCad(or alternative programs) the key issue for me is that it is a conglomeration of programs by different parties required to work together to equate to the same feature set of Eagle. KiCad has some nice features and I'm still working out how to do Eagle-things in KiCad. But seriously, I suspect many people will stick with Eagle because it's a good price point. The subscription model does work out to a higher price, especially if you take into account an amortization for those who buy a copy and basically use it for 5-8 years and finally get around to upgrading a few versions down the line.
Having been an Adobe Creative Cloud subscriber for a couple of years now, I find the stream of updates that comes down the pipe is actually a Good Thing(tm) as I'm making incremental updates vs large version upgrades.
But that's just my 2 cents. For some folks, there is a much higher price sensitivity. I see myself subscribing to the $15/month model(maybe switch to $100/year to save that $60/year).
What I hope to see from Autodesk for the continued subscription model, though, is a matched continual stream of updates that improves the product. Things like a clean and well maintained components library that one can sync between machines/installations. Expansion to cover various kinds of components. Better searching. PCB templates for common board times: PC104, PCI, PCIe, BeagleBone Capes, etc. etc.
I tried the 3d imaging service and there are so few components in there that it's more or less a blocky rendering at this point. I would like to see it expand to cover more components so that it's a seamless experience.
Just my 2 cents.
