I use my iPad2 for everything. I just bookmark it and return when ever I want. Upper left corner, click on the box with the arrow. Then Add bookmark, when you want to return, just tap on the open book next to the arrow box and you'll find Whatnext.

You can make your own app. Be on the site you want and tap on the box with arrow and select add to home screen.There you'll have a little icon box for this site on the home screen. I don't even use my laptop anymore, It's so easy and convenient having the iPad. I Hope that helped.
