My 85 year old mother inlaw is living proof of this. For years both my
wife and I have tried to get her going on a desktop computer with no
real success to speak of. We got her and iPad a couple of years ago, and
she took to it amazingly fast. She now uses it to read and send email,
browse the web, and participate on FaceBook. Truly amazing. She says
there's just something about simply touching what you want with a finger
is so much easier for her.

your statement that even sighted folks work more efficiently with mouse and
keyboard than touch-screen is completely inaccurate. This is a field which is
constantly and thoroughly being studied. Research papers are published
extremely regularly on the topic.
First, when touch-screen interfaces are used in information kiosks rather than
visual displays with keypads and navigation devices, user error is reduced from
18-25% to 6-10%. And, this is consistent across every topic / field which has
been studied thus far.
Second, the world record for fastest typing speed on a mobile device in 2011
was held by a person using a touch-screen device. I have not checked more
recent numbers, but considering all the other studies I have analysed over the
past few years, I would not be surprised if touch-screen devices continue
holding speed records for data entry.
Third, there is an upper limit on how many keyboard command shortcuts a person
is able to maintain in one's active memory. Touch-screens, on the other hand,
with their immediate visual response to haptic activation, do not suffer from
the same limitation.
It is comforting for us to tell ourselves that sighted people do better with
keyboards just like we do. However, even though we know people who match what
we wish so much to believe, research from around the world is continually
proving the opposite to actually be the case.

Hi
On the other hand many gamers want precise and immediate interaction and
there are plenty of game controllers for the idevices available. I doupt
anyone has said that they just are not get used to the touchscreen:-)
Unfortunately until Apple puts any effort to general keyboard usability on IOS
devices these keypads do not help much except for making flicking and double
tapping faster and more prddictable. Apples's 1D approach for screen
navigation is extremely inefficient. 2D-way, exploring the screen with one
finger is faster but for efficient use one heve to memorize all the controls
on every screen of any application he/she uses.
It is a bit unfair to compare mobile phones to desktop computers but even
sighted ones works more efficiently with keyboard than mouse/touchscreen.
Using the touch screen as blind is similar to using an failing keyboard: you
have every time check that the key press gets through and it was the correct
key that wenth trough.
