I don't own the phone, but I do own a 2235, and I have looked at this
phone pretty closely at a store.

Pros:
1.  Allows 2 NAMs finally.
2.  Power cables are compatible.
3.  BREW ?
4.  911 ?
5.  EMS support
6.  They've expanded the debug screen information.
7.  Added support for specific ringers per contact, and image.

The things I disliked the most were the features that Kyocera lists in
the manual on their web site, but VZW decided to change/remove for
some reason.

Cons:
1.  According to the manual, the phone ships with 2 games, but not the
VZW version.  Most likely a way to sell BREW stuff?

2.  My 2235 is very convenient, because the shortcut keys make sense.
Not anymore.  For some reason, they decided the web browser and access
to brew were more important than locking or silencing the phone.  This
will probably be the main reason I won't upgrade to this phone, even
since I've been anticipating it.

3.  Data kits are not compatible with older phone models.  Not that
big of deal.

4.  Screen is very dark when it is not lit.  I can usually see the
display on my 2235 without hitting a key to turn on the backlight.
You pretty much have to hit a key on the KX414, otherwise it is too
dark to read.

5.  Still can't chose between PCS and Cellular 800 bands, but at least
you can still force it to Digital only.

All in all, the screen isn't very big, and it was hard to get a good
feel for the color quality, since they removed the two stock games!
The screen is basically the same size as the 2235, with the same
number of lines on the screen.  Like I said, I use the silence and
lock shortcuts, right and left of the nav key many times a day.  The
lack of this feature alone will most likely keep me from upgrading to
this phone.  Otherwise, with the addition of the extra NAM, I would've
already purchased the phone if it wasn't for the stupid marketing
decision on the shortcut key.  The extra NAM would allow me to use the
phone at home, since I could setup the second NAM to use Sprint only.

I've already asked CS about reprogramming the keys with the PST
software, but they said Kyocera wrote the software specifically for
VZW and it can't be changed.  Does anyone have information to the
contrary?  Does anyone know how this phone compares to the same model
released by other carriers?  Are the features exactly the same, or do
the carriers in fact make this many changes to the stock software?
