If they do announce in Jan and ship in April (probably quicker this time), then Blackberry might not look as good in comparison. I really don't get why you would tip off your competition unless they are counting on a lot of companies doing budgeting for this new device.
Well, Iām not sure how much Apple could or would want to change the next iPad at this point in time. At any rate, 2011 will be an exciting year for tablets.
They will probably add the front facing camera and probably the next generation of A4 to keep up with the summer iPhone / fall iPod touch.
If they go the iPod evolution route, I expect to see a price drop to put more pressure on the low-end. I still dream of a dock / network sync that will allow people not to have to own another computer.
