i don't have a computer at home (just an iPad that's on the fritz). i have everything on my work computer including 54 gb of iTunes and every picture i've ever taken of my 4 year old. i need to get it off and i'm looking for an external hard drive. i think 1 TB should be enough. where can i get a good one. also- what makes a good one 'good' per se? am i looking for lightweight? why yes or no? i have no experience in this area, clearly. any help would be appreciated.
