The comparison with BMW was perhaps a touch unfortunate -:)
However, just to take the issue of the tablet (or maybe tablets) itself. It would of course be logical for Nokia to launch a tablet that has both wifi and 3G and that begs the question of which form factor they are like to use. I would not be amazed if they offered something in the 7 - 8 inch category as well as a 10 incher. The next question is which architecture they are likely to use. One could argue that ARM is an obvious choice if they aimed primarily at the consumer market but given that one of their major marketing strengths is in the business sector that suggests x86. Anyone got any ideas which way they might jump?
