Update 2: Turns out, it's actually Android, NOT Windows Phone 8. Apparently, the Lenovo rep demoing the K900 here on the showfloor was misinformed and misled the press in attendance by insisting this was a WP8 device (despite our protestations). We've since amended the post above and added a new hands-on video below to reflect that correction.
Unfortunately, the IdeaPhone K900 is not slated for U.S. release, and when I asked a Lenovo representative if it could possibly reach the U.S., he said “probably not.” The phone will start selling in China in April and it will later hit India, Indonesia, Vietnam, Russia, and the Philippines.
If this is the new Clovertrail+ reference phone then Bell has done very well with the specs. This will allow any carrier to compete successfully with the more expensive iPhone5 or S-III/IV. As always Intel is providing the most genuine disruptive competition in any market it enters. The real story here is not ARM breaking up a x86 monopoly (which isn't true anyway with AMD/VIA around) but Intel breaking up the ARM monopoly in phones and tablets. The market and ANALysts have got this soooo wrong, they have the hunter and the hunted and actual market battleground in the actual real world reverse order ;-).
Haswell and 7W Ivy Bridges will make A15 look very under performing and hot this year in tablets and Clovertrail+ will be as good as any high-end ARM superphone in performance, life and features.
