I hate Gmail. I have Google and all their products... even the good ones.
You have Google and all their products or hate Google and all their products?
Why don't you like them? I'm neutral actually. If they work I use them, if not I figure what do you want for nothing. For example I have one client with a dozen or so employees that use Google calendar in iCal and share calendars. It's been a few years and it always has had glitches, can't find the server for some accounts, but always with only an account or two, not all at once, which always irons out in a short time.
They just got Filemaker Server to host their databases instead of Filemaker Pro so were going to put a calendar on there for local and remote access. It's supposed to be a solid solution, you get what you pay for.
