Z10 looks nice, but not sure BB10 is enough of a step from N9.

Plus I have lots of questions about this new platform. I imagine these will only be answered once someone has a device to play with, they aren't the type of things the reviewers seem interested in.

1) Does BB10 support multiple Exchange accounts via EAS
2) Does BB10 Balance need BES, or can it simply be enabled by the user and then they connect work to one Exchange via EAS and home to Gmail or whatever...
3) What is Google support like? CalDAV/CardDAV/IMAP?
4) Can multiple Calendars be synced?
5) Can multiple Contact service be synced (Exchange/CardDAV?)
6) IF exchange policy requests PIN, does BB10 prompt for PIN on wake up, or on switch to Work profile?
7) Other questions I haven't thought of yet!

PS. And it appears now that even MS are going to support CalDAV/CardDAV. And Google extend EAS support until July (that might be good for us Harmatten users too )
