I've got Windows Outlook as I used it for years when I was still working, and was familiar with it. It has email, calendar, tasks and contacts functions which are easy to use IMO, but I started using it a long time ago. It now costs about $100/yr, you can't just buy a "copy" of it and use it forever like days gone past. You "rent" it but the newer version is very similar to the earlier versions. Very low learning curve for me so that is why I stayed with Outlook.
