Latest Kantar Worldpanel Report is out (OS Marketshares in last 12 weeks)
you'll have to click on it to make it viewable. basically it calculates marketshares based on sales volume over 12 weeks. As WP8 has been out for only 4-5 weeks (with availability still increasing), I think the figures are quite interesting.
UK has bumped up from 1.7 to 5.1% (hopefully should hit 7-8% by February)
USA has gone from 2.1% to 2.7%
Germany's fallen =(
Italy's gone from 3.6% to 11.8%
Spain 0.4% to 3.0%
i'd say its a fair-to-middling report. not astonishing levels of growth, but it is there.
