i tried the Targus Vuescape for Ipad 2 at Best Buy and it did not quite fit the Ipad 3 so ordered the new one from Amazon-due Wed. A friend had had one for the Ipad 2 for a year and says hers fits the 3 but probably because it has stretched just that small amount by being used for a year and taking it in and out.
I have a Propup for the Ipad 1 which is too big for my 3 but Propup generously is replacing mine. They said they should fit all Ipads from original to 3. I love mine for reading in bed and in handsfree reading and typing sitting in a chair as I'm doing now.
edit: Got the Vuescape this afternoon and like it very much. It has 3 good viewing angles--two on one side with the slots to hold up Ipad--and one of them is terrific using the BT keyboard. To use the lower angle I like for onscreen typing, you turn the cover over and use the tab above the stylus holder (which won't hold my Adonit Jot or not easily) which slips between the Ipad and the cover and holds it securely in the lower angle. Its relatively light, slim, secure. Good value for the money I think.
