I'd like to see the PIM/PDA/Phone features take a huge step towards being serious business apps instead of "touch" toys. Sorry for the nasty tone, but I bought the N900 thinking and hoping that for the price and given the platform OS and the general state of the art (Palm, Blackberry, WinMo,etc.), it would be a serious business tool. But so far, it is a disappointing mess.

There are many large and small examples of this:

- I have over 3000 contacts on the N900 and performance in the Contacts app is very slow. I had pretty much the same contact list in my old Palm III and it performed a lot faster. Part of the problem is the N900 tries to search while you're entering the search key, which means you don't even see what you typed until AFTER it finds the search results. This maybe cool for small numbers of contacts, it's royal pain when you have 3000.

- no global searching / sorting through tasks, notes, calendar. I have over 200 notes in the N900 (synced from Outlook) and the only way I can find things is to scroll them serially. That's just terrible design.

- no categories.

- cannot edit a contact from the call history. I have to leave the Phone app and start the Contacts app, refind the contact, make the change.

- no idea what number the caller called you with, so you can call back at the same number

- Outlook to N900 syncing through Nokia PC Suite stops working when the database gets large like mine.

- Calendar doesn't support very common, but albet complex repeats, like 4th Tuesday of every month.

- when setting a date, the device doesn't even display the day of week for you or a mini-calendar selector. Just some silly odometer-style touch wheels.

I could go on, but the point is the built-in PIM/PDA/Phone suite is not ready for business users. Many of my complaints have been filed as bugs or enhancement requests by myself and others, but I'm not confident the built-in PIM/PDA/Phone package can be "bug fixed" into shape or if Nokia is motivated to make a truly killer business app.

So I'm looking for a competitive package I can load on the N900 to replace the built-in package. Does anyone know of one?
