My company has switched us over to Gmail from our exchange server. The client we used for our email, Pegasus, was a bear when it came to large files, and by large I mean 512kb plus. It would halt our computers till the file finished downloading. Due to the nature of my job in particular I receive larger files 3mb + on a fairly regular basis, for me using Pegasus was quite frustrating. The move over to gmail and google docs has been a delight. If I have a large file, I don't have to email it, just send a share request for others who need access to it. Over all I think it's a nice idea, but as mentioned, what happens when google sells out...
