OK, so let me show my ignorance here. What would I need to buy from the ground up to get something like this?
Right now our environment is 3 laptops, 1 desktop in the office. About 5 users max (for a while at least). Our email is hosted by Google Apps for your domain, and we have Host Excellence as our web server.
If I wanted to get an Exchange or "Exchange like" solution (i.e. push email to mobile devices (iPhone), push calendar, etc.) what would I need to get? Hardware? Software? Do I need to do something with our email (where it is hosted)? Keep in mind that I don't need a real high powered solution, and don't want to spend thousands.
I am really coming in on this from the bottom level.
I'll admit to being a bit obtuse on the latest tech initiatives, but why all the push for "push." Can't you simulate push by setting your handheld to check emails more often, like, say, every five minutes? If you are in an active email exchange, can't you refresh manually?
I agree that push is cool, but I think the Exchange server approach is a big step backwards, especially considering the costs. Plus, I hear that gmail is working on integrating push capability for iPhones and it may come out within a few months anyway. For a small office like yours, it seems overkill to spend a lot of money on an Exchange server, particularly when Google and others are working day and night to make these things obsolete. (But as usual, I'm probably missing something).
In the mean time, maybe forwarding to a mobile.me account could be a decent solution:
