Chrome on the iPad has one important feature.
It fixes an apple problem.
You cannot use iCloud.com in safari on ios, this is a f**king major pain in the ass if you are using somebody else's iPad and you want to check your mail. (Think travelling abroad)
Fortunate chrome has a "request desktop site" which allows you to log into iCloud and read your emails. Large chunks of it are broken, but at least you can check your mail.
Apple really need to do a mobile compatible version of iCloud for this very reason.
