Not for keyboard

No it does not fit the ipad 4. It is specific made for ipad air

It fits the iPad Air (1st Gen)

Yes

This unit fits the Apple iPod Air.

This cover will not fit an iPad 4. I had an iPad 4 and it is too large for this cover.

Use a leather cleaner but just a dab of it. I have a white one also and use the cleaner that I use for my car seats.

Use a magic eraser, looks like new.

I use a dry erase sponge

Try a cotton ball/pad with a little rubbing alcohol. Also, windex makes an all-purpose cleaner with vinegar - works great!

Not sure, the apple case is clam shell style but I prefer this one and only use other when traveling

I found the Fabri Skin Keyboard Folio by Logitech works great for me. It's very lite and the keyboard is real smooth and easy to type on.I'm also waiting for the clamshell case for the ipad air to make its day view.

This one is probably the closest: http://www.bestbuy.com/site/zagg-zaggkeys-folio-case-and-bluetooth-keyboard-for-apple-ipad-air-black/1712904.p?id=1219062285111&skuId=1712904&cmp=RMX

This one is for the iPad Air. The other models of Zagg keyboards don't really resemble the Clam Case at all in my opinion.

This one has a hinge that allows viewing at almost any angle and it stays open at that angle. It also has the keyboard set back a little bit so it leaves a ledge in the front to rest your hands on like the Clam Case. It is a whole lot lighter than the Clam Case though, which is a huge plus.

Not sure, but if you were to contact Samsung directly, they could probably answer that question.

Probably not. Best way to look online.

Not sure what you,re questioning, the I pad is secure inside folio with straps you just flip the cover open and you simply unfold to stand at different angle.

Yes
