I love my iPad but it generally is not that great in sunlight, and as has been noted, can be virtually unreadable. It is very sensitive to the natural lighting conditions. However, with polarized sunglasses I found the screen nearly black when in portrait mode, yet surprisingly bright and usable when in landscape. You might try that and see if that helps in your situation before investing in other things.
