I am very interested in sailfish as I find the concept persuasive in a way that is not true for other platforms. However, I am holding off buying a Jolla phone until I am confident of a few things.

My first worry was the new interface may not be easy to use. However, recent articles persuade me that it is basically good, even if there is room for improvement. So that is one box checked.

My next worry is email clients. My primary use for my mobile phone is email, and my main account is hosted on my work exchange server. There was some feedback yesterday on this site that one of the recent patches improved the way the email client works with exchange. Is anyone using an exchange account heavily and able to report that the client is robust under heavy use?

My third worry is the calendar. Does the calendar work well with an exchange sever? Can invitations be sent and accepted/rejected? Does it update smoothly? Is it easy (ergonomic) to add events? Is it easy to see what is in the calendar for a given day? Does the phone alert you with sound when the next meeting is approaching over the horizon?

My fourth worry is document viewers (word, excel, pdf). Has anyone tried these out? If so, how well do they work?

My fifth worry is LDAP. To make the phone easy to use at work, I need to be able to look up phone numbers of colleagues on the LDAP server. Has anyone tried this? If so, how well does it work?

My sixth worry is the keyboard? My current phone is an aging, decaying blackberry curve. The keyboard is not perfect, but I find it easy enough to use. I say this to indicate I have little experience of onscreen keyboards. How does the one in Sailfish compare to others? There seem to be many calls for Swype. Is this indicative of weaknesses or just user preference?

I guess this will do for now. Thanks in advance for any information.
