i think everybody agrees that the mass (the american idol watching guys, not us) wants a slim device (without a hwkb) and nokia wants to sell as many phones as possible, so i agree with nokia that their decision is the best to make money and to (maybe) "disrupt" the market.
my advice for hwkb-lovers: buy the device, regardless of having the hwkb or not. If the N9 (without hwkb) sells well, nokia could thing about a sucessor (or "sister" model) with a keyboard. but if it doesnt sell well, nokia would be confirmed about their decision going wp.
So, if you want a maemo/meego device next year, buy a maemo/meego phone this year and hope for a big hit.
