Yes! The new design is amazing! Siri is better, basically everything is accessable, etc. Although, FYI, it does take up a lot of space; 3 GB so if you have very little room left on your device, I wouldn't update. Also, it does take a little getting used to.
Yes, it is! I just installed the iOS7 beta2 on my iphone 4s. It performs well on 4s. Actually, you can even install iOS7 on iphone4 and even 3GS. I heard the iOS7 is slow and stuck on iphone4 or earlier iphone edition. But it definitely works fine on 4s!

im not sure but i think only iphones and ipod touch 5th generation can get the ios7 update but im not sure.
If 3 plums = 2 apples, then 24 plums = 16 apples: 24 ÷ 3 = 8, then multiply 8 x 2 = 16.
Nope. Just the 5th Generation.
You cannot change a computer into a phone
iOS7 automatically shows you how much battery you have left. If you don't have iOS7 then activate VoiceOver and tap on the battery image on your screen. It will read aloud how much battery you have left.
iphones do it is under settings and general (except from ios6 and ios7)
