it is suggested that one has a laptop, they even give the minimum specs that it should have:
128mb ram, 500mhz processor, windows me, 6gb hard drive, 100mb zip, floppy, and cd rom 24X, dial up modem, and usb port, ethernet, 110-230 v power supply (most new laptops already come with adapter that will use 110-230 v), etc
i also read somewhere, i can't find it now, that costumes charges 5% tax to bring one into the country . . . so if you bring one, i would be prepared to shell out some money. my laptop cost about $2000, so i am going to have at least $100 us to make sure.
a surge proctecter is a must as well, we are talking third world here, definitely a likely possibility for power to surge . . .
if you have any more questions, i would call the new york office, they have an 800 number . . .
best of luck
