I'm really tired of the excuse that 'WP is only ... months old...' It was unveiled in June 2012 and released in October. Look, MS had all the information in the world available to them to make the OS anyway they wanted to and they 'should have' released the OS with the most up to date features. Instead they decided to do it 'their' way. What they didn't account for is if people start coming over from other OS platforms they're going to want some of what they feel are the 'basics'. What these people fail to realise is that WP is a completely striped back to the barebones OS with 'integrated' software that was suppose to implement things differently. WP OS is a very basic OS solely for the purpose of being able to run smoothly without clutter. Part of the issues that have arisen on WP is the fact that it's too different and basic for some people. The other is that it wasn't a 'complete' OS on release. They rushed it and stuffed up some things up along the way. Other issues tend to be with apps, it seems that a lot of apps have issues, regardless of the lack of them.
Now before anyone harps on me about being negative, I actually want the bloody thing to do well because I like it. I also think as users we should be the OS's toughest critics and MS should be listening to us. I know some people are 100% happy with WP as is, that's fine, however there have been too many small issues that should haven't never been (i.e.: music + video) the other being features that should never have been missing in the first place (i.e. attaching multiple documents to an email or reply email).
Also to clarify your statement. GDR2, then GDR3, then WP8.1. The GDRs are mostly bug fixes and extensions to exisiting software (I don't see HD as a 'new' feature). I don't see us getting any additional features of any sort until WP8.1, in otherwords 1st quarter sometime in 2014. That doesn't mean we won't get anything at all in GDR3 I just don't think we should get our hopes up too high, GDR2 should be proof of that.
All in all we all want the best for WP, I think those of us on it who may complain would like to see it get better, I just think there's a lot of people who are cautious of what MS plans are. We really have no idea where WP is heading. What needs to happen is for us to just let the updates happen and see what comes of it. If at that point WP doesn't suit you go somewhere else. I have no qualms with changing OS. I like the fact we have choice in the market and I hope more people will take up this type of thinking. Just because you like WP, if it's not doing it for you then take a break from it and then come back when it hopefully does. No point being frustrated by 'not getting your way' with a multibillion dollar corporation.
