I would like to update my iPad Mini 1 since it seems like it should be so ancient now (it's had 3 iterations since then), but dammit if the thing still doesn't just work fine. Yeah, it feels a little slow for some things now (especially browsing the internet, can't seem to keep more than one or two tabs in memory), but it's still super solid and gets the job done, and even still works with the vast majority of apps and games. I might have to soon to be able to iOS dev with the newest XCode, but that's the only reason I have. I've owned that thing for almost 4 years now. It's probably the most solid piece of hardware I've ever owned.
