One of the things I was only belatedly appreciative about Lotus notes was the experience on Linux. While I was at IBM, I used Lotus notes on Windows, then on Linux. The Linux version did occasionally crash; but overall the experience was similar to a Windows user.

The next company I worked at used Exchange, and developers could use Outlook webmail or an IMAP client like Thunderbird. I found this experience to be substandard; both from a perspective of consistency with managers who had Outlook and found calendaring to be pretty awful compared to Lotus notes.

This might be less important now that you can have your Calendar integrated into your smart phone, but I did not have a smart phone at the time.
