[8525, TyTN, MDA Vario II, JasJam General] V J:
My first experiences with the TyTn also were disappointing. It took me weeks to get it more or less useable, and even now some things are not as convenient as they were on my Symbian phone. Here are the things that bother me (some are solved by 3rd party applications, others are not):

General:

- onscreen keyboard pops up even when one is using the hardware keyboard

- no way to backup all the settings

- often hard to navigate when not wanting to use the stylus

- only one language for text entry (word completion and transcriber)

- no data counter (gprs traffic)

- wordcompletion intervenes too much (when I type a Dutch word "wel", after typing the space after the word it changes it to we'll, no way to prevent this)

- wordcompletion only shows one possible next word (no way to scroll between different candidates)

- any setting that is slightly more advanced or deviates from tradition is either hard to set or impossible

Messaging:

- no way to specify the imap-root folder

- not possible to switch SMTP servers (even the from field cannot be chosen when sending a mail, nor can mails be moved from one outbox to another) (other mail clients I tried have problems with my VPN)

- cumbersome downloading (headers only: one has to open a mail and then choose to download it, then click send/receive; why not download it when this is chosen? or even when it is openend?)

- many notifications for sms (sent notification in messaging client, sent notification from network, receipt notification) when sending messages (and one cannot mark them as "read" from the todayscreen)

- applications are not very well integrated (e.g. file explorer cannot send a file via bluetooth)

Calendar:

- always opens on day view, would like to change this to month view (but is not possible)

- day view should be scrolled down to show the start of the day (e.g. 8.00 at the top of the screen), now I have to scroll from 00.00 down before I can see stuff)

- cumbersome entry of time (esp. when entering times that deviate from the time slots)

Phone:

- no support for different call profiles (where a profile is essentially a call filter)

- when one contact has multiple numbers, the phone application only shows the last used one

Network:

- when you add a VPN server, then delete it, you can't add one with the same name (even though it has been deleted)

- wifi starts detecting all networks, and does not necessarily start with the networks one has been connected to in the past

Bluetooth:

- limited profiles

- sometimes counterintuitive

ActiveSync:

- sees the device as new every now and then (causing it to say it conflicts); I have to delete the device on my PC and let it find it all over again

Programs folder:

- is alphabetically, would be nice if one could order this to his own liking

Alarm:

- no snooze function

- unnatural way of entering time and repeat options

File explorer

- no way to view extensions of files

I've learned to live with some of these problems, but I would have expected Windows mobile to be a more mature system. I had to choose a WM5 device (so I new I had to compromise), due to the fact that I wanted to run some specific application (PocketFMS), but didn't anticipate I had to compensate this much. (of course, no of my issues is purely HTC related, but will be present on all WM5 devices)

In total, I personally consider Symbian (Series 60) to be more efficient, better customisable (one is less forced to do things one way) and (never thought I'd say this) more stable.
