Okay, I’m not a big gadget guy and I’m pretty clueless about most things tech. But, the iPad looks like it might be fun having around. So, I’m hoping some of the tech savvy amongst you can help me out. As far as storage: can I compare the amount I will need with the amount that my iPhone is using? That is, will X number of songs/photos/apps take up the same amount of space on an iPad as they will on an iPhone? Also, I have no video downloaded on my iPhone. I assume that requires much more space than a similar amount of audio. Is there any sort of “rule of thumb” I can figure on when comparing the requirements of a movie vs. music? (Can I just figure that an hour of video will require X times the amount of space as an hour of audio?) Also, I can’t really think of a reason that I’d need one with cellular service. Wifi at home…wifi at work…wifi at friends/sister/parents/on the plane/in the hotels etc. Is there some really compelling reason – that for some reason is escaping me – for me to get one with the 4G? Many thanks!
