It depends.  There are three different survey data collection software
packages for the 48, none that I know of for the 95.  Special ruggedized
cases are available for the 48 ranging from a ziplock bag to a gas
tight rigid box ready for tripod mounting.  The design of the 95 makes
it more difficult to make special cases for it much less operate inside
a ziplock.

The 95 also runs MS-DOS, which some people don't like at all.  I merely
cope with it.

   Certainly more powerful, that may or may not be better.

   Much cheaper, more powerful in some ways than a 95 with Derive.
>    - the 48 is better for the purpose than a full-sized personal computer
   Much cheaper and much more portable.

I've sometimes wished for a 48 in addition to my 95, but I wouldn't use
it enough to be worth it.

It depends.  Should someone sell the 48 to afford to buy a
subnotebook?  A subnotebook is non-divisible so it's always going to be
about twice the weight and size of of either a 95 or 48.  Battery life
is very low on some of them, they tend to be fragile.  They all run
MS-DOS.  I don't think there is one best computer for anyone much less
everyone.

I'm not very familiar with either, I'm only saying what others have
said.  I'll keep what you've said in mind.

There's also Mercury and Symbmath.  Of those only Derive is fully
functional on a 95 so the choice is between either Derive or a 48, if
someone wants a compact package.  Even when more software gets ported
to the 95, and more powerful/cheaper/smaller palmtops come out, the 48
is still going to be cheaper.

I meant the latter.
Less powerful pocket computer are so much less expensive than larger
computers that getting these functions when you buy the other stuff in
a larger computer is almost an insignificant factor.
It works both ways.

I actually meant a jacket pocket, although I have seen people stuff a
48 in a pants pocket.  A notebook computer takes up most of the space
in a backpack (I take one to school every day).  If most people won't
bring a notebook to school everyday, then how can a cheap
calc+expensive notebook = expensive calc?  Half the time the notebook
won't be available.

I don't feel that a 48 is the best possible choice of a pocket machine,
but merely that it is one choice from a wide spectrum of machine
choices.  The 48 is a hybrid between calculators and computers and
occupies a price niche between the two ranges.  Some people need that
particular niche filled, others don't.  You advocate a specific ratio
of portable:desktop computer power and say that a particular niche
shouldn't be filled at all.  I'd rather be more flexible.

A 2400bps data and 9600bps fax modem is shipping now or soon for the
95, a Zeos version will be available at some point.  Other companies
are working on modems for these machines as well.  These are not PCMCIA
2.0 devices, rather that are proprietary devices specifically made to
get around the limitations of PCMCIA 1.0.
