At risk of feeding some trolls here... What Nokia do not seem to understand is the success of a platform/os is largely determined by what applications are available for it. I'm not suggesting or in-fact agreeing with the original poster who started this thread. Considering how many apps were available at launch was pretty impressive. When Goggle launched the Android platform a couple of years ago only a handful of apps were available at the time. What I've just said seems to contradict my first paragraph but I Nokia need to take a long-term view of this. If the next version of maemo is not compatible with the n900 then users and app developers are going to be p***** off with Nokia. Why? It means tweaking your developed app to run properly on the next version of maemo when you could be spending that time improving your app. If maemo 6 will not run on the n900 and you are a current owner you will have to buy a new device and start your nice app collection from scratch. If Nokia had any sense of the current smartphone market (and it's long-term future) Nokia would ensure that the maemo 6 platform will also run on the n900. If Nokia cannot make maemo 6 backward-compatible and force n900 users to buy a new phone (the n900 here is £500ish) to benefit from the new apps then Nokia will be forced-out of the smartphone market entirely. Apple and Google will eat Nokia's dwindling marketshare instead. I only bought my n900 in December last year. If Nokia want me to buy a new phone to get the latest version of maemo then I will simply go elsewhere. If Nokia expect people to buy a £500 phone and 9-12 months later buy another phone at £500 then the management at Nokia are more ******ed than I thought. If Nokia want to grow marketshare and remain as a big player in the mobile phone industry: 1) Ensure the previous phone can run the new updated os 2) Keep user and developers happy - user's library of applications will grow and allow user's to take the applications to the new phone too 3) This will attract more developers and more users to Nokia maemo-based devices 4) Third-party app developers may gain the confidence to charge users for apps if they wanted to. Nokia get revenue stream.
