Whilst I can see some people being annoyed that they wouldn't get the full update to Windows 8, it is more up to the people that purchased the phone prior to this announcement. Personally I would ask myself why I chose this particular phone was it because I really really really wanted a Windows 8 phone and wanted to get a going with a phone asap, or was it because I liked the Nokia and the current OS more than I liked the other OS's or I wanted to try something different. If the 2nd/3rd scenario was the case and I was enjoying the user experience, then the fact that there will be an update coming to 7.8 may not be something that I would be too worried about, and I would certainly want to ensure that if I do update to 7.8 it would not change my experience for the worst. As far as going to Windows 8 I would probably be happy to wait. It is all a matter of what a person really wants from the tech gear.
It is a similar point of view for RIM. Currently I am considering changing one of my phones to a Bold 9900, it is on OS7 not BB10 and will never go to BB10. Why would I do this, simply because I like the keyboard on the Bold and it would be specifically a work phone, the OS would work for what I want and I would have no problem that something new is to come out in a few months. Now having said that I do want to try BB10 which I believe I will have the opportunity to do on the Playbook and also if I decide to upgrade the other phone I may move to a BB10, or another OS. Similarly as I have a really fast computer tower, when my personal notebook dies I am likely to purchase the pro version of Microsoft Surface rather than another notebook or ultrabook, this is not a Playbook replacement rather a notebook replacement specifically for traveling having 128 Gb drive.
So what am I saying here, choose your gear carefully to suite your requirements, then it should not worry you if some new software comes out 6 months down the road. If what you choose works well why should you worry. New software/phones/computers will be developed on a daily basis, it is not possible to continue to update/upgrade to every new toy. As I mentioned in another post I want to replace my camera, I have been considering this for a couple of years (yes that's right 2 years) during which time several new Nikon's (which is the DSLR I use) have come out, I have looked at the specs of each new model, I am not worried by budget although I would find it hard to justify spending $4000 for a body as I am not a professional, but looking at each model and what they can or cannot do, and what I want to do with it, plus taking into consideration weight, looks, quality, pixel density etc, I am still looking at the D90 which is far from the latest and greatest but it does everything I would want or need, plus it is coming down in price because it has been out for a while.
The various tech articles will center on the latest and greatest and highlight the people that are upset but will never focus on the majority that are happy with what they have and will probably not even upgrade to the next compatible OS, for one reason and one reason only they need to encourage people to spend money on the next big thing because if they don't the authors of the articles will have nothing to write about
