I'm an electronics engineer by profession, but in a different field (ASIC/MCU design). I have been doing circuit boards on a hobby basis for about 10 years, most of them ends up not being finished or are ongoing projects (never had time to finish). Most of these boards are simple boards and dont require fancy features. Since the boards usually are small I have been using Eagle for these (free version). Since I learned Eagle first I just ended sticking with it for hobby projects as I did not want to spend a lot of time learning new tools for each design I did. Eagle for the most OK, but could be a bit hard to use in some cases (as I did not spend time to learn it proficient). At my first summer internship I was making PCBs for a company, and I used Protel99se I think it was. It was a new world, but of course too expensive for hobby use. I probably did a couple of designs in Protel and later a few designs in Altium for this company, so I got semi proficient in using it.
The fact that I now can use a similar tool for free is great IMO. I know how to use it, and I dont have the limitations of Eagle. Most of my hobby projects I dont mind being public. In fact I think it is great as this made it much easier to make the project public. No hassle with setting up a site for my project, uploading files and similar. Great. But I also have projects that I dont want to have public, mostly due to the fact that I spent a lot of time on these, and I would like to get something back if I make it public.
In any case I had to try it. This my experiences after a short project import from an eagle project.
Register, download and install took about 3-4 minutes (I have 50/15 Mbps download/upload), no issues.
Setting up and importing eagle project was not a big problem, except that I had to install a newer version of eagle and update my eagle files to new format. Import process was all most OK. I did lose some silkscreen graphics that I had added in eagle. I didn't spend time on checking the status of the board and schematic, but it looked OK at first glance. As good as one can expect I guess.
Committing files worked OK. Releasing seems to be OK* also (did not spend much time configuring it). Release name ended up with a stupid long unreadable string. There should be some option to set a release version number or something and add a release comment (same as for commit). I guess this will be fixed.
So given that it is a beta, I think it has potential, but:
-Keyboard shortcuts!!! it freaks me out that it is not the same as in AD. Please allow me to be partly effective at least (happy to pay a few $$ for shortcuts)
-Internet access, great if I can get an offline mode, but for me its not critical. If my internet is down I'm doing something else. it wont kill me
-Local only project, yes I want it, happy to pay $$ for it.
-It must be possible to have several projects with the same "readable" name in the community (if I got Dave right, this was not possible).
And the price have to be right for the different features. I for sure wont spend a lot of $$ on PCB software as I'm not using it a lot and I cant defend the cost when it is anything close to $1000. It would then be much cheaper for me to buy all the things I otherwise would make myself (it probably already is...).
