The open source Maemo platform, which is used on Nokia's Internet Tablet devices, will soon support Trolltech's Qt development toolkit.

After a delay of several weeks, Nokia is finally shipping its Maemo Linux-based N900 smartphone for 500 Euros ($750), says eWEEK. Meanwhile, a research note supports rumors of an upcoming Maemo-based, mass-market smartphone designed to compete directly with the iPhone, says an industry report, and LWN.net reports on last month's Maemo Summit.

Users who have bought Nokia's flagship smartphone, the Maemo-based N900, won't be able to upgrade the device to MeeGo, Nokia said in a blog post. The MeeGo OS, merges Intel's Moblin and Nokia's Maemo Linux-based operating systems.

The N900 will be Nokia's first and last Maemo 5 smartphone, with the next version due to run the new MeeGo Linux mobile OS created as a joint venture between Nokia and Intel.

At the Maemo Summit Conference in Amsterdam, Nokia gave out over 300 N900 phones running Maemo 5. The N900 is the successor to the N810, over a hundred of which were handed out at Akademy a year ago. Read on for some opinions about the N900 and the results of 3 days of hacking.

At the Maemo Conference in Amsterdam Suresh Chande announced that Nokia has contracted KO GmbH to write a mobile office viewer using the KOffice libraries. The presentation by Suresh was given with the Nokia N900 smartphone, using the new Office Viewer. The improvements in KOffice have largely been in the libraries, on top of which a Maemo-specific GUI was written.

Nokia has released Version 4.6 of its Qt cross-platform application and UI framework. Qt 4.6 includes support for the Symbian platform for the first time, and adds Windows 7, Apple Mac OS 10.6 (Snow Leopard), and the upcoming Maemo 6 to the list of Qt-supported platforms.

Intel and Nokia are merging their open source Linux operating systems to create a MeeGo OS, designed for mobile devices ranging from handhelds to netbooks. Hosted by the Linux Foundation, MeeGo builds upon the core from the Intel-backed Moblin technology and adds Nokia's Maemo middleware elements, as well as Nokia's Qt application framework.

Nokia will introduce Qt to the maemo platform in addition to GTK+. The plan is in the earliest stage and recruitment offers for Qt/C++ developers will pop up soon. Don't expect any Qt application developed by Nokia for the tablets anytime soon, though. The first actual step will be the distribution of the Qt libraries for application development in maemo.org during 4Q2008.
