Kimmer:
Different strokes for . . .
My stable of Mac products is now serving a quite specialized function as my life and activities are more restricted by the exigencies of age.
I got my 1stGen iPad on about Week 1, enjoying it immensely until my arthritic fingers couldn't manipulate the KB I bought from Kensington, initially to accomplish typing at reasonable speed.
Because I am now with Lil during much of her waking hours while she reads and watches TV (her computing, so important to her for so many years is now increasingly difficult for her), my getting/answering MAIL, Googling the 'net, etc are now increasingly important to me. The iPad, while VERY portable, just wasn't enough "computer" which is what led me to an MB-Air that, thus far, is THE solution. Absolutely Perfect, which turned out to be such a surprise.
Full-size KB, dazzling display/wonderfully large FaceTime/speedy internet connection/fast printing when I need it/etc./etc./etc. all are "there" @ just over 2 lbs. No HD is simply a non-issue, since networking with my trusty iMac is so fast and easy.
The iPad has become a large, easy to read, TV remote with the help of this nifty app . . .
.
My 4s iPhone is invaluable (as a phone) primarily because it's "Blue-toothed" to my hearing instruments via a streamer manufactured by the hearing aid company, AND as a wonderful camera that has "retired" all previous cameras. No need for any other bells-or-whistles for us these days.
Not that "one-size fits all" by any means, but the MB-Air is far more important to us these days than an iPad ever could achieve.
