Retired computer applications teacher who has always flirted with Apple but been faithful to PC until now. So anxious to get my hands on an iPad, BUT don't know if I should buy an iPad1 or an iPad2; or 3G; or 16 or 32 or 64 . . . Heading off for a five month adventure in Central and South America and want to travel lightly. Will use it for Internet contact, reading books, storing digital photos, listening to music and taking care of business at home. What do you experts recommend? Pleez, someone give advice. Thx, too.
