It's important that PDA takes out and it can be used immediately, otherwise it does not become instead of a system notebook.
A
system notebook does not requied any batteries...
10 years ago, I had worked at semicondoctor sales devision
while training period. I saw a mobile, small wordprocesser
trial-production at meeting with Japanese wordprocesser
engineers. Although the word-processor special-purpose
machine of the Mobile did not come out to the market, an
attendee of the meeting, semiconductor engineer, have a big
system notebook . A wordprocesser engineer said "It is
smaller than your notebook ." He answered "But, it works without
batteries."
and he had taken laughter.
The
mobile in these days spends much energy, additionally boots
up slowly.... If you was asked appoint from someone and
checked schedule with such mobile, you should have askd him
to wait a minutes.
But, the case of palm/pilot is not inapplicable. Palm/Pilot
has four physicall buttons which are used to run assigned
software and also works as a power-up button. Palm/Pilot, it
is taken out and can be used immediately.
If
it is avaricious and it is going to give multifunctioness,
compactness and operativity required for PDA will be lost.
Palm/Pilot -- it is really precious PDA.
