For my iPad I found the best case was the one made by Apple.
Apple iPad Case - Apple Store (U.S.)
- simple
- inexpensive
- cleanable/washable exterior that is not expensive leather or something else you will worry about getting dirty or damaging
- soft microfiber interior makes sure the iPad doesn't slip around and provides some impact resistence
- folding flap provides an excellent stand for typing, etc.
Unfortunately, the iPad2 is smaller in length (-1 mm) / breadth (-4 mm) and much thinner (-4.6 mm), so if it doesn't actually fall out of the iPad1 case it will at least slide around too much. Plus the rear camera is covered.
I dearly hope Apple also produce an iPad2 case like the basic iPad1 case, with smaller dimensions and camera holes, etc., but in the same basic material/design.
I'm not convinced the smart covers are a good idea, whilst being trendy and cool, the back is completely unprotected (although this may be a conscious decision on Apple's part to avoid heat build-up if using a closed case? - although my iPad1 doesn't have an issue).
Plus there is the issue of travelling/carrying the iPad2 - the iPad1 basic case sort of conceals the device - it's completely covered so there is some protection against drops and scratching the back, and it also looks like a (paper) notebook so less tempting for people to steal. With the new covers the iPad is clearly visible and identifiable.
I could go for a 3rd party case if Apple don't do the right thing, but it's just not the same, and usually much more expensive. In addition, they tend to look too glitzy (trying to promote themselves, I guess) and bulk the iPad up too much. Basically, the Apple case is perfect for iPad1 (IMHO), so I just hope there will be the same option for iPad2.
But sucker that I am I will no doubt get the iPad2 fairly soon, regardless of case!
