I have a four-year-old iPad 2 that has been extremely reliable for a long time, but is starting to creak in many ways. I'm usually frugal with my electronic devices, but I think it's going to finally need replacing this year. Most likely, I'd go for another full-sized iPad rather than a Mini, but I don't want or need the extra-large model that's rumored to be coming later this year. Also, I've never maxed out my 32 GB iPad 2, and would probably go for 64 GB rather than 128 GB with a new model. * Any suggestions on whether it's better to go ahead and get an iPad Air 2 now, or to try to make my old iPad 2 last until the new models come out in the fall? * My iPad 2 has cellular + wifi capability, which was invaluable for international travel in 2011 and 2012. However, I haven't traveled that much in the last couple of years, so I don't know how easy it is to get free or low-cost wifi access outside North America these days. Is cellular capability still as useful for travelers as it was in 2011, or is it better for an infrequent traveler to spend the money on additional storage instead?
