Good for entering numbers, bad for entering text.
This number-centric keypad was not designed for rapid text entry and
requires too much thinking, pausing, and button pushing to enter text quickly.
Typing text on this keypad is so tedious that most people
won't use it to store names and numbers in their cell phones, much less to type an email.
Even with disambiguation algorithms, 10-15 WPM are typical
typing speeds on this keypad.
Surprisingly, typing on a simple, 26+ button alphabetically ordered keypad is a
painfully slow and punishing experience.
We often "stall" when looking for the
next letter we want to type.
That's because alphabetic layouts are totally
different than the PC keyboard (QWERTY) layout we have spent so many hours using.
When typing on an alphabetically ordered keypad,

For instance, we are used to seeing and reaching
for the letter "Q" in the upper-left corner of our keyboard, but on any
alphabetically ordered keypad, the letter "Q" is somewhere near the bottom.
It's like trying to write your name upside-down.

On a Delta II keypad, you fly.
the letter "Q" is where you expect it to be.
The Delta II speed matrix immediately boosts your typing
speed three to four times faster than a cell phone keypad and twice

That's 20 to 30+ WPM typing speeds - straight out of the
This is possible because letters on Delta II keypads are

Delta II combines your PC keyboard experience and motor
memory reflexes to your advantage.
Within minutes, you are cruising, typing even faster.
Your mind is quickly completing the connection between your
PC keyboard and the Delta II keypad.
What a huge difference the right layout makes.
