Forgive the question... I am definitely not trying to be rude or accusatory.
I have been watching SME for a while, I see you have jumped up a full version since I last looked.
How many small businesses (~10-20 users) are using SME for their primary server? I have been an MS shop putting in SBS for a long time... but I have been able to change about 90% over to linux (thanks Ubuntu!) for my desktop and my servers. I have not deployed any linux SBS killers for a couple years, and then it was ClarkConnect (now max 10 mailboxes... sad). I just wanted to get a feel for how much SME is utilized and if it is actively being developed, bugchecked and maintained.
The main site has never been really well maintained that I have seen (latest news July 22 2007), but then again... my site has nearly a year old content too

. But it gives me reason for pause.
So, if willing, chime in and tell me why you think SME would be a good fit for small sub 20 user networks for basic email and file sharing (PDC emulation). What obstacles have you see/overcome? I have about 2 weeks to make a decision for one client whose *really old* scsi backplane died... getting them a new server and considering backing off of SBS since they don't use anything but mail storage.
Thanks!
