This debate is very old Ian, and Samsung didn't actually get sued for anything in the end! I purchased a Samsung Note 10.1 Tablet the new 2014 Edition and it blows the iPad out of the water!!! Was comparing it with an iPad Air the other day side by side and the Samsung has so much tech in comparison that the Air is not even at the same level, the only thing I can say the iPad Air is better is that its slightly lighter, but boring as hell. The argument of Apple has more Apps is no longer valid so now there is just no argument!
At the end of the day Apple does well what its meant for, making a call, sending a text/email, using the odd app, playing some music, with very little customization (people can't mess around with it, so less prone to going wrong), all Android phones do that and plus some more (but you can customize the hell out of the phone and therefore its more likely for the user to mess it up, not because of Android, just because of the flexibility it gives the user).
All I know is that my next phone will most likely be Samsung Note, there is simply no better device out there.
Alastair have you taken a look at the Nexus phones? The Nexus 5 is now available for £240 off contract! They don't have any bloatware from carrier or manufacturer and Google always release the latest OS for those devices first (equivalent of the Apple OS releases).
BTW I don't care what anyone buys to be honest lol they all have their pros and cons and its up to the user to evaluate all of the features and buy the best device for their own personal needs and not what anyone else says.
