that was quick - thank you Jonathan "Nokia has a policy on the (former) Internet Tablets to offer an upgrade to the following version of the OS, which has been the case on every device since the original 770 was released (back when it was OS 2007, 2008 etc). We were told at Nokia World (last September) that this would continue on the N900 and its successors. It seems likely that the next two models (one which is going to be a netbook design) will have Maemo 6, upgradeable to 7. At this point, the N900 would be on 6 and theoretically have no further support. Having said that, Nokia has usually continued support for longer than you'd expect. I suppose with Apple and Google/Android now offering free upgrades on an ongoing basis, Nokia will find it harder to simply say something is end of life as quickly as they have done before. I hope this helps! Regards, Jonathan Morris Editor, What Mobile magazine & online"
