So, as every sensible person has been saying...
iPad two announced a year after iPad 1. Guessing availability in the US in April, again, a twelve month upgrade cycle.
And for those people on here who are meant to have a vague grasp of technology, please stop this ridiculous nonsense about 'retina' display. It's not technically possible, unless u want to fry an egg on the screen and have a ninety eight second battery life and also it's not necessary, the iPad display is beautiful. It has the resolution of a seventeen inch display of a couple of years ago, but with roughly twice the pixel density.
Larger harder drive, battery life improved even further, maybe a ram jump. Probably lighter and thinner. If u want more than that, look elsewhere. This device will continue to sell in the tens of millions in spite of the baseless criticism of the users of these forums.
