Like several others I picked up Android and iOS basic for free during the promotion. Never actually used them, but having basic iOS I think meant I could get the upgrade to Pro iOS for cheaper, so bought that when upgrading from Unity 3 to 4. Which has been great since i’ve started doing some AR apps on iOS, so I think it worked out well for all concerned.
I’m not sure I would ever have bought the basic versions though, I feel if I needed those platforms I’d probably just go Pro straight off. However what I did like was when basic was free as it gave me a non-time limited ability to play or test them out which I could only really get otherwise by registering a new Unity trial or requesting a trial.
I think the Basic versions are useful though, firstly for those who don’t need all the Pro features as it offers a lower entry price, and it means Unity can do stuff like the free promotion, which defiantly gained favour with myself and did more or less lead me to investing in iOS Pro.
However what i’d really like to see are completely free versions of Android, iOS and Flash Pro, but where they are heavily restricted to prevent commercial use. So maybe time trial on published projects (not the addons), time limit per run (e.g. 15 mins), heavily watermark, with a constant full screen overlay etc. Stuff that makes them impractical for use in a any sense commercial or otherwise, but perfect for trying out and getting to grips with these systems.
For example I have had several projects where I would be tempted to try and publish them to Flash. However although the Flash beta was impressive I found very few of my projects would compile or be usable without serious changes to the codebase. Further more I felt that without having an eye on developing projects to be published to Flash and therefore be able to test out Flash publishing periodically that trying to do so at the end of development is rarely going to work.
Having a free version of Flash Pro even with severe restrictions built in towards being unusable for an actual release would be perfect. As I could develop projects from the start to support Flash publishing and then offer the client the opportunity to switch at the end of the project. At which point I could purchase the Pro upgrade safe in the knowledge that the project will compile and build without any additional effort.
Of course in a commercial environment it only take a few projects to make it viable to purchase Flash Pro anyway, but in the case of Flash and I think mobile too, the risk of buying it upfront without knowing if the projects are going to be suitable is a bit high. Obviously Adobe’s change of heart on the licensing also helps greatly for the case of publishing to Flash too.
