I know that this has been discussed in several threads, but will hereby try and gather and update the info: For some days now, several app makers have sent to my iPad 2 an option of upgrading "the old" (not-Retina) app with an upgrade that, often among other features, also make the app fit the new iPad's Retina display. So far, I have been reluctant to carry out the upgrade - for instance, i read in a post that the Pages upgrade (with "Retina Display files" in the upgrade) would demand MUCH more storage on the iPad, and as I have an iPad 2 this would of course not be a benefit for me - on the contrary: Much more space taken away without getting something positive back. Is there a general advice, then, to avoid such Retina Display upgrades for a device (e.g. iPad 2) that doesn't take the advantage of the "RD-files/upgrade" anyway? Of course: there may also other reasons to upgrade, but if these reasons are not strong ones, should one just keep the app on the iPad 2 as it is, without the Retina Display upgrade?
