I have only one question - when NG2 will be released? Because now it is not possible build real applications, many libraries are not stable, and still in beta or rc... Four month I'm trying to do real application and I must say that it was my big mistake when I decided use Ng2., with every new release I always have troubles with some dependencies or with new API, and there are no many stable components which I can use without pain. Ng2 has good promotion however we need wait official release., and then make some conclusions about it.
I've been working on an enterprise app with Angular 2 for over a month now and it's been mostly ok. I think the only horrible problem was the change in the form framework that went largely undocumented (super secret doc: https://docs.google.com/document/u/1/d/1RIezQqE4aEhBRmArIAS1...)
Once you get to forms 0.2.0 and rc4 of everything else; the framework is beautiful and even though I hated Angular 1.x with a passion, Angular 2 is awesome.
The uncertainty over this question is one of the reasons my team decided to build our new application in Angular 1.5 (though using TS and Webpack). It's less fancy, but mostly rock-solid and well-supported and understood.
We'll upgrade in a year or two once Angular 2 is well-understood and all the 3rd-party libraries have updated or deprecated into something else. The course looks like a good way to start understanding the differences.
Watching the milestone burndown on github for RC5 looks like it should be here pretty soon (two weeks-ish maybe is my guess), after that it appears the team will be on the last sprint.
I've been writing a few greenfield apps on NG2 since late alhpas and the thrash from RC0 thru RC3 was pretty painful but now playing with the new Router and Forms I get the feeling that the pain was worth it. Things seem relatively stable in RC4 and I really like the Router and Forms apis.
I am staying away from the Angular CLI since I reallllly want the bundling and tree shaking but am moving forward without it for now since it is using the old Router and Forms libs. In my opinion the CLI is the only tool I wouldn't bother until NG2 is done and fully out of RC mode.
I am still optimistic that NG2 is the right solution long term.
