You crazy man!! Remember how good the iPhone 4's screen looked in relation to the 3GS?
I reckon there significant enough upgrades to make purchasing the new Pad mandatory

Retina display, processor, camera and LTE = winner
Retina Display: 90% of what I use an iPad for involves text, not pictures. Reading it, writing it. I can read my iPad 1 perfectly well. I am not an artist or a gamer.
Processor: Yes, nice, very nice. Most of that extra horsepower is used to drive the new screen though, so it's a zero-sum game in the end.
Camera: No flasher. OK for taking pictures on the beach (which is where Apple cunningly shot their promo film), but you'll still be carrying something else for nighttime or inside photos. For rugged outdoursmen types only, then.
LTE: Yeah, right, And our cellcos will introduce 4g to South Africa right about when the rest of the world is about to move on to 5g. And probably do it on a frequency that is incompatible with anybody else on the planet. Little-known fact: before we can get 4g, we need to move on to all-digital TV to clear the analog frequencies, and you know how many times THAT has been postponed. LTE is not even relevant to Europe, so how you can call it a plus in a South African context baffles me.
What was I hoping for in the new iPad? Storage. I regard it as scandalous that they stuck to 64 GB as the maximum. I wanted 128 or 256. Heck no, I
need 128 or 256. I
want a Terabyte iPad

. Don't give me the "keep it in the cloud" bulldust. If I am in a motel room in Koekenaap, I want my data with me, not on a server in South Dakota. And repeated calls to download the same data from da clowd over and over again only enriches the cellcos.
So, if I can save a few thousand on an iPad 2, I have to give it serious consideration. For what I want to use it for, the iPad 2 will give me the exact same functionality.
I haven't made up my mind yet. The new one will give me a degree of future-proofing as developers slowly start to abandon the 1024x768 format in about 2 years or so. The fact that Apple kept their prices steady is a plus point. Whether Core will do the same is an open question, of course.
