While rest of the world is ogling on touchscreen smartphones and netbooks, Nokia is quietly working on Maemo mobile OS for Internet Tablets and Smartphones. MobileCrunch got lucky to leak out a Maemo "Harmattan" OS screenshot from Nokia Labs. Filled with selectable widgets, Nokia's Maemo Harmattan is also being speculated for supporting ads from mobile service providers. Nokia's Maemo is Linux-kernel based mobile OS meant for Nokia N810 tablet like devices and smartphones. According to MobileCrunch, the blue section the screenshot's background is the static on which the widgets float on a scrollable page.
Nokia Maemo's Harmattan Build has been rebuilt for the phones. The "Harmattan Homescreen UI" is big scrollable page where in users can add or remove widgets.
The floating widgets appearing on the screenshot are tied up to the phone. For instance, any change appearing in the Contacts, say adding birth date to an existing contact, will automatically reflected in the Calendar widget.
However, the ad-supported mobile service provider widgets cannot be removed or customized. These ads would be pumping in deals using the GPS feature of the smartphone. Suppose you're walking across a mall, then you'd be getting ads about current deals offered in the outlets.
No confirmed date of Maemo Harmattan release has been announced as yet but it's expected in fourth quarter of 2010 or the first quarter of 2011. Obviously, more screenshots of the future builds will soon be out, either leaked or official.
