nokia 6230i or sony ericsson k750i

Pls help me decide between nokia 6230i and sony ericsson k750i. I've always been a nokia user since 1993 which is why i'm quite hesitant about the se k750i even if i know it's a great phone. i'd like to know how the nokia 6230i compares to it in terms of camera, calendar/calendar notes/reminders, connectivity, expandable memory, general ease of use especially in sending sms,mms.

thanks.
