2013 will be a crucial year for Windows mobile software, according to IDC. IDC analysts say developer support is critical and mobile platforms that fall below 50% in support from developers 'very interested' in developing apps for them are likely to see a gradual demise. IDC's quarterly surveys of more than 4800 mobile apps developers shows Windows 8 tablets having such support from 33% of developers and Windows phone 7 software having 21% support. Research in Motion (RIM) has a mere 9% support for Blackberry phones and 8% for the PlayBook tablet. The figures for Apple iPhone are 85% and iPad are 83%, followed by Android phone 76%, Android tablet 66%.
