Qil asked a question. What is a PIM 'suite'. I for one do not know. BUT I know what everyone who drools on my N800 wants. Sidenote: "Yes I spout off about this is an internet device for your life, not a PDA."
But the things I think people want in a PIM suite

• Calendar with Alarms.
• Email app that integrates with calendar.
• A SINGLE address book with convienent interafces to hold all data about contacs and spawn off appropriate applications. IE email, phone, IM, sip address, physical address.
• Synchronization with MS Exchange. I know this is contentious, but I would even accept a commerical product that works even if I had to pay for the addon. Sadly many companies use Exchange for email and calendaring. I have enough trouble manually syncing Kontact to our server, I can't handle another sync job
• ToDo List.
• Note taker.
• Finally, a method of linking the data together.

So how to do it? I don't know. I seriously wonder though if the status quo PDA methods are right. IE: Link-n-Sync to your PCs that have some syncing SW. Instead I'd like to start thinking about something more Internet Tablet focused.

My unformed thought is something akin to but not schedule world. But online storage. Maybe like Google Calendar + custom App on the N800/770. Keep a cache of data available on the device and sync it up/down when online.
This blog is long enogh, but I'll try to form this idea a bit more later.

Sorry for the wasted bytes.
