Hi – and thanks to all who have commented. I actually did write a reply after Colins post, but like an idiot forgot to post it so it is lost. Never Mind.
Quite reassuring that some of you have had iPads and iPhones with cracked screens and carried on no worries for years in some cases.
I think Micheal G's Infixit teardown of an iPad Pro is the one I have got, but the thought of actually stripping it down scares me!
I do like the idea of a screen protector but.
The screen I have is cracked and breaking up in only one corner and mostly on the little black margin there anyway, plus several cracks across the screen, and a screen protector might just hold it all together. If it lasts another 3 years then it will be due a renewal then anyway. I think Apple are quoting about £400-450 for a screen repair over the phone.
I am going to their "Genius Bar" next week with my wife's MacBook Air which has a touchpad problem so will get an upto date quote then, but the screen protector option at about a tenner is looking good at the moment!!
