I was thrilled when Apple announced the iPad 3. I was in love, I ordered it so that I could receive it on day one...that was the last time that I ordered an iPad one day one.
The damn thing was heavy and thick. Not to mention that it would get extremely warm (I had the iPad 2 for 2-3 months until I sold it for 90% of what I paid for it) compared to the iPad 2. It was sluggish (not just gaming), like opening safari was noticeably sluggish. It was a mistake, Apple realized that it had created a monster and decided to end its fate by releasing the iPad 4 less than 7 months later.
It's the Vista of iPads
It was less than 10 pct heavier. The CPU was the same as the ipad 2, which loaded pages just fine. The processor at its hottest was no more than warm water. Let's not overblow the issues.
