Nokia has said that shipments of 3G internet tablet the N900, which began yesterday, would fill pre-order volumes, meaning the device would not be in retail outlets until later this month.
The N900 integrates the Maemo 5 OS, an upgrade of the Maemo OS running on previous Nokia internet tablets that did not feature calling connectivity. The new software allows users to run several application windows simultaneously.
The device includes a full slide-out QWERTY keyboard, 32GB of memory, a five-megapixel camera with LED flash, GPS, and Wi-Fi.
It will be compatible with most networks at launch, although not initially with new 3G SIM cards from 3, although a software update is due before the end of the year.
Nokia Nseries vice president José-Luis Martinez said: “We believe the Nokia N900 will be a very compelling device for people who are passionate about technology. What’s exciting is the Maemo software, which takes its cues from the desktop computer and offers a full browsing experience like no other handset.”
