Lots of good info and people on this forum; but the rumors of when the iPad comes out, and the facts when they are finally announced will be pretty much the same here as any other news or blog site. This is not Apple leak central.
Then again, there are usually at least a few threads going where people can discuss and expand on those rumors. Me, I prefer to wait and see what actually happens, but I understand the urge to speculate and dream. Apple's product announcements are just a bit like Christmas, several times a year.
Stick around for a while. I'm sure you'll like the place.
There is lots of good advice and info on here plus plenty of members all too willing to help with any problems.
Remember, search is your friend. If you can't find the answer you need and you post a question then give as much info as you can to help members help you i.e. iPad 1 or 2, iOS version and name of app if the problem is with a specific app........and please don't forget to read the rules http://www.ipadforums.net/forum-rules-help-info/2119-forum-rules-everybody-please-read.html
You can download the manual for your iPad here http://support.apple.com/manuals/ and in iBooks search for "iPad user guide for" and you will find free comprehensive manuals for both iOS 4 and 5.
