Diego Doval wonders if he should push spaces (to keep it simple: a PIM on steroids) on a professionaly supported software side. The market of PIMs is really a niche, with to my knowledge, three major players: Lotus Notes, Palm Desktop and Microsoft Outlook. Among the three, two are usually given by your company (yes, somebody is giving money to Microsoft so as you can have the crappy Outlook on your desktop) and the third one is free on Palm site, and distributed with every machine running PalmOS. My personnal configuration is this one:

• personnal mail: outlook express (configured for a long time, quite stable, not bothered enough to switch)
• professional mail: outlook (company policy), replicated on my PDA
• agenda/todo/memo: palm desktop (rarely used, it is used as a backend for my Clie, but I find it quicker to start the Clie to do something than to launch Palm Desktop)
• newsgroups: gnus (oort)
• newsfeeds: feedreader (but it crashed)... so I'm looking for a replacement (knowing that I don't want to install a .net runtime on my machine, and I've already tried newsmonster, amphetadesk, sitescooper, and others for which I forgot the name... I should give a try to Kommunist one day and mess with the code)

I'm not really in an all-in-one approach, and one thing is sure, I won't use a PIM which can't be synchronised with my Palm. If I decide to switch to an all-in-one approach, it's going to be a revolutionary process :-)
