You can teach an old dog new tricks. But behavioural change is a completely different story!
I got a new IPhone 5s today. You can walk out of the store with it fully operational, and I did!
BUT re-downloading the apps, creating folders for them and basically making it thumb happy for me takes some time.
Plus reconnecting/relogging into them all is a chore! But I think I’m done…carrying the IPhone 4s with me just in case!
