Its your own opinion you like the ipad the ipad 2, you buy you don't, its that easy. And there will always be a few defects in stuff, someone does not do a job right. Has to be something good about them as they are selling enough of them. I wanted the new bits they added and found them worth getting a new one, i got twice the memory and it cost me 50 quid more than my first, good news for me.
And my point at the start was that whatever you buy, people are going to expect more than they get, your never going to get it as it is held back for the next model. You will land up when the ipad 3 comes out there will be people saying well it should have had this that and more, ill wait for the next. If you can justify to yourself then thats all that matters. Have a great time with which everone you guys have or like.
I don't think Apple is holding back for something to put in the next model. Here's why I think that way. Apple is in the process of developing cutting edge technology ... look at the combo GSM/CDMA special chip it takes time and effort, testing to do that. It just wasn't available til this fall. Apple is implementing Thunderbolt in all their desktop and high performance laptops, including AIR. They hold a patent on the concepts to put Thunderbolt in iPad via an adapter. Now they just have to add the controllers to make it all operate. And remember one thing, it is the software that makes Apple so much better. iOS5 is coming ... but it will be September. There are no other computers with Thunderbolt offered. Before you know it, Apple's will be transferring back and forth at warp speed, while the rest are still diddling along with USB2.0 ... OMG.
So it is all about working towards their master plan. Most of the competitors didn't even start til Apple had sold 15 million units in a market segment that didn't even exist. Now Apple is leading, and has a huge head start. So when you say they are holding back, it is only because it takes time to put out a finished product and full support. The competition is scrambling to play catchup with not ready for market offers. Look at Xoom, Galaxy, Playbook, etc. Enough, but you get the drift.
