I found this very amusing (and useful) advice!  8)

"This is the dilemma I faced.
Here's what I discovered:

The desktop PC is designed for people with two hands to get work done.

The tablet/smartphone/social media is designed to be a content delivery
vehicle for people with a short attention span and lots of cash.
You get peer pressure from your friends to buy stuff and pay by the byte
to have it delivered to your device so you can pay by the byte to use it.
You're encouraged to share every damn thing you ever do for a nominal cost
per byte.

So, first thing to decide is how big it should be.
Do you want it to fit in your pocket?  If so, measure your pocket and
get a device that fits.  Unless you have clown pockets, you'll be limited
to something not much bigger than a smart phone.

If you want something bigger, figger out how big and find a paperback
book that size.
Lay several $100 bills on top and cover them with a piece of thin glass.
Tape it all together.  Carry it around everywhere you go and never put
it down.
It'll be as big and heavy and fragile as a tablet and just as annoying to
carry around.
And, due to the money under the glass, it will look exactly like a
real tablet
to every thief within viewing distance.  Good luck getting it back if
you leave it on the counter at Starbucks.

Now, what are you gonna do with it?
Try this experiment.
Cut a rectangular hole in a piece of cardboard the size of your tablet
screen.  Tape it over the face of your desktop monitor.  Adjust the screen
resolution to give you about the same number of pixels as the tablet.
If there isn't one already there, download an on-screen keyboard.

While holding your fake tablet in one hand to keep it occupied,
use the other hand to operate the mouse to do what you expect you'll
be doing on the tablet.  No fair touching the real keyboard.

If you haven't given up by now, move on the the connection.
You either pay for a 4G data plan and get something that looks to the
network like a smartphone,
OR
You rely on wi-fi hot spots.

I live in a metropolitan area.  We have a zillion free, hot spots.
But there never, ever, seems to be one where I am.

I have a number of PDA's and smart phones with wi-fi.
They're plenty fast to surf the web and read email.
Some even have 640x480 screens.  I thought I'd be happy.
Battery life is too short to use as music players.
I'm never near a hot-spot when I'd like to connect to the web.
I tried carrying one around, but found it just in the way.
Went back to mp3 player with field-replaceable AAA battery.

I bought a 7" android tablet at a swapmeet for a dollar.  I was elated...
until I got it home and tried to use it.  I want my dollar back.
It's slow and cumbersome to use.  It's a Chinese knock-off.  They
didn't pay the fee, so Android Market won't let me in.
Stuff I found outside the Android Market is full of ads that
take up way too much of the screen.  The OS version is too old
to be compatible with most apps.
If you do buy one, make darn sure it's the expensive licensed
variety that can hook up to Android Market and the OS version
is recent enough to run the apps there.  There ain't no free lunch.
And you've still got the problem of how do I get hooked to the interweb.

Either a smartphone/pda or tablet will let you scribble notes on the screen.

The next step up is the small PC.  I picked up an Asus EEEPC 900
at a garage sale.  I cringed at the $10 price, but what the heck.
It's a real computer.  Once I got a better version of linux on it.
it's quite useful.
Runs real apps the way I'm used to interacting.
Once you get past a size that fits in your shirt pocket,
size is no longer your primary concern.  1-pound, 2-pounds, who cares.
It's a sit-down machine with a keyboard.  So you won't be texting
as you walk down the street into traffic.

I found two problems with it.  The keyboard is small. You can
get used to typing on a small keyboard.  Problem is, that when I got
back home to the big keyboard, I couldn't type on it.  Switching between
different key spacings really hurts your typing speed/accuracy.

And I still needed a hot spot to make it work outside the house.
And I can't draw on the screen.

It sits here right beside me on the charger.  I haven't
actually turned it on in months.

If you have money to burn, go buy an iPad and a data plan.
If you just wanna dabble, go down to the electronics recycler.
They have a dumpster full of old smartphones and PDA's.
My favorite for this kind of stuff is the Dell Axim X51v.
If you want a camera, there are some nice cheap Palms.
I like the treo 850.  It's a palm with a windows OS.
But the screen is smaller than I like.
I've bought several under $10 each.  But there are many others
with wifi that can work.

I have a friend who has a tiny laptop computer that he tethers to
the unlimited 4G phone that is paid for by his employer.
If you can swing free access, that's the way to go.

You can pay big bux for something that will be obsolete by the
time you get it home...and mostly sit on the shelf.
Or you can get something dirt cheap that was obsolete five years ago and
still sits nicely on that shelf.

Are we having fun yet?"
