Hi folks,
Thank you all for your experiences and feedback. Even though the actual product won't be released in retail channels for awhile, we wish to help nonprofits and libraries make informed decisions by gathering questions and concerns, regardless of whether it is through our donation channel. There certainly is a lot of excitement building around this latest version, and there seem to be genuine user experience improvements in 7 in the beta and release candidate (RC) versions. That said, the actual product features and policies may still change until release, or even after release when patches inevitably are released.
@orangehabitat: while I don't have the answer to this (and maybe other folks who has a RC can verify), I am inclined to believe that there will still be a 10 connection limit to 7, as there has been for windows 2000, XP, and vista (professional or premium editions). If anything, with the emergence of Windows Home Server and Windows Server Foundation as viable minimalist servers, they could even lower the limit. If all you need is file sharing you can use a Network Attached Storage (NAS) device, or use an old computer and turn that into a NAS via something like www.freenas.org
