- one less navigation button. the button in the center of the four directions ("OK") was used in the e815 to navigate into things and change them. in the w755 interface it's more frequently used for saving and exiting. this is a frustrating change.
- i haven't found a way to assign ring tones to groups of contacts. i had all my contacts in groups, with a ringer for each group. i can still assign ringers per person, but i don't really want to diddle with that much info.
- nine member group maximum. arbitrary and useless.
- no three digit speed dials.
- buttons are harder to push.
- buttons reach closer to the edge of the phone, causing thumb strain.
- no more viewing contacts by category.
- on the e815, many text fields would do something sane if you started typing into them. on the w755, they sit there looking dumb.
- the w755 thinks every new appointment you put in is going to start at 9:00 PM and end at 9:30 PM.
- every time you put in a new appointment, you have to tell the w755 you want to use iTAP to enter it. the e815 had a setting for this, for each kind of entry field. that meant setting it 8 times - but i never had to mess with it again.
- on the e815 the microSD card is hot-swappable. on the w755 you have to take the battery out to get to it.
- i had to move the files around on the microSD for the w755 to see them.
things that are cool:
- more interface themes
- vibrator feedback when you press the touch buttons on the front
- "in case of emergency" built into phone
- hold down numbers to speed dial, e.g. hold 6 instead of 6, #, Send
- USB charge port
