There is a 'normal timing': not by exact dates, but by days.There's no "normal time". It can be announced with availability that day/week or announced with pre-orders for later delivery. It's different for every announcement.
Even though it's already pretty much a given that a new model is coming in the next month or two, I'd be really surprised if they let everyone know for sure what to expect next and then make us wait any longer than a week, with the iPad 2 sitting around in stores with a newfound inferiority complex.The gist of what I've been reading lately is announcement in early Feb, with release in late Feb/early March.
Yes, I agree with you. I have both iPad and galaxy tab 8.9 - I prefer the iPad aspect ratio. It would be nice if android tablets start following this16:9 and 16:10 is great for watching movies but nothing else. Anything portrait mode is awful, and you just can't read a 16:10 book.
