But if he doesn’t need a new one urgently right now, then why not wait a few more weeks? The user experience likely won‘t change much for him with the new model, but that absolutely doesn‘t mean that there won‘t be long-term benefits.
In a year or two it won‘t matter for him if he held out on the device 3 weeks longer, but what will matter over time is the faster and better hardware. The new iPad which will likely come with a faster processor and other improvements will hold up much better a few years down the road, the performance difference won‘t matter right now but it can absolutely become noticeable a few years later. Just look at how many people experience lags and slowdowns all over the place on the iPhone 6 whereas the 6s with a faster processor and an additional gig of RAM holds up mostly fine performance-wise. Even if you‘re not big into technology, chances are you still don‘t like waiting for apps to load or looking at lagging animations.
Remember, OP was on an iPad 2 for 6 years, it‘s likely that he intends to get a similarly long usage time out of the new device, so why not choose the device that‘s more futureproof for (likely) about the same price? By not waiting the additional three weeks, he would be giving up an entire year of future-proofing, that might be one year less that he‘s able to use the new device. This additional year would definitely win for me over these three weeks.
(Three weeks is just an estimate here, we don’t know the exact release but the rumors strongly suggest that we‘ll see new iPads in less than a month. It would be different if we didn‘t have such a concrete and soon release window.)
And yes, if I knew that I‘ll get a better and more future-proof model of a hairdryer or refrigerator I‘m looking to buy for the exact amount of money and „only“ three weeks of delay, then I would most likely wait as long as my old one is still usable until then.
