For small shops (and maybe large ones) the BES incompatibilities could be a non-issue since the BB10 devices support ActiveSync. Unless you are pushing policies, apps, etc...ActiveSync will be more than enough. You can do all the fun stuff with ActiveSync like remote wipe, turn off syncing, enforce passcodes, etc.
I personally can't wait to get a Q10. I have a 9900 now that my boss has tried to replace multiple time. NO! When an 18 year old comments on how fast I type on my 9900, I know I have the right phone.
Plus I have an iPhone 5. I can't type on that thing to save my life. It's for media, web and other non-work related playing.
