We've been here before and this time wont be the last, I imagine
Some of my friends and acquaintances are comics fans, and some of them enjoy digital comics. Only one uses an I-Pad. The rest, for the most part use Samsung devices and a couple have other android slabs but I forget what brands. I have no problem with the weight of my Samsung 10 inch tablet, nor do I know if an Apple one is lighter or heavier. It never entered my head to consider and I-Pad, mainly because of the storage problem. I have 2 micro S D cards, each 32 GB, which I switch around as required and my pal Vince has a small credit card sized card thingy, with slots, which holds 8 micro SD cards. So neither of us is filling up our internal memories.
The only way round the major space problem with an I-Pad is to use their cloud storage. That is what they want you to do. Me, and many others just do not want to do that.
By the way, the quality of reproduction on a (clean) Samsung screen is excellent and I read American downloads form sites such as DCM, Manga and piles of British B&W comics of all different shapes and sizes. Something like Perfect Viewer lets you adjust the page to fit the screen. And for the most part, it works well.
