The Iphone Safari was always behind the Ipad one but for me it's the worst part of the new IOS7. It's got too much blue bars and logos. Even Safari in IOS6 adding tabs actually slowed it down not sure about Ipad 4 but does for Ipad 3. If you use Icab and disable all the top bars it's like IOS5 and Ipad 1 and loads sharper and faster. There's some third party browsers run similar apps to the old IOS6 which give good comparison. Safari is very similar to Google Chrome only Chrome seems more polished. Luckily Safari always seems to get a redesign so I hope in IOS8 and 9 they improve it. Over all IOS7 does go with the current times, some of it's brilliant some of it's just copying rivals but there's this divide of people who love or hate IOS7. I suppose it's the same every year but IOS7 really makes products like Iphone 4 slow.
