powerbook or ibook?

[Rosemary Horton]

I'm seriously considering getting a laptop. The main reason is for 
presentations vi digital projectors at conferences  often connecting to 
the net and for working on websites. What should I consider ibook or 
powerbook?
Someone suggested there's not a direct connector to a projector from an 
ibook and the memory wasn't good enough to run a presentation.
If I want to connect using ibook or powerbook to a windows network with 
a mac machine, how difficult is it? Do I need extra hardware or 
software?
Not all places are enlightened enough to have mac networks.
Can I share my adsl connection through my imac to an ibook or powerbook 
relatively easily? What extra stuff will I need to buy?
