Hi
So they got me on the way back from Brussels this year and I bought a IPad Air 1st generation, for about 200 pounds, new from Know How at the airport, and so about 150 pounds cheaper than the UK price as well. I decided to buy one since hadn't really done anything as such with iOS and wanted to really, and the price seemed good for a IPad Air, and even with the IPad Air 2 out.
So I have been using it quite a bit the last few months here and there, but it has unfortunately also fallen on a hard lamented floor a few times, resulting in cracks on the top right corner plastic, with a little hole in it even, but still worked. However just before doing this email it's just gone for it's worse fall whilst taking it from one room to another with a few things, and getting distracted by the dogs, and it fell on a hard tiled floor face down. Now there are cracks going around a lot of it, and part of the plastic seems like it could easily come off, and there are now quite a few cracks on the screen as well, but it still works, doing this email from it in fact.
It seems that can take it to a Apple store and have Apple replace it with the exact same model, for quite a bit more than I originally paid for this one, but still quite a bit cheaper than the standard UK price. Is that what I really want to do? Of course not. I was also chatting a few weeks ago to someone from an Apple re seller in Bristol on the phone, and they were saying how an IPad isn't really a fixable device or as such, but I know that isn't quite true. Also I think I would rather get this one fixed for cheap enough, then get it replaced with the exact same model, so any suggestions on how to do that would be appreciated. If I knew more about fixing hardware I guess I could attempt it myself, but that is not the case. Well it's a tablet that been only really using at home at times since getting, but I'll bring it along to the LUG this Saturday as well for some advice. If this kind of thing happens to my soon to finally have Jolla tablet I would be more annoyed. It's kind of funny also in a way that this happens to the IPad which apparently is meant to be so great, but well Apple is just a brand really. Also I bought the Loop tablet on a crowd funding campaign, and apparently that's meant to be more resistant to breaking like this, well I hope that's true :), and I don't have that just yet. Apparently with the Loop tablet a five year old could throw it around the room without it just braking.
Regards
Sebastian
P,S
Also got a cheap Android tablet that can't charge any more, but I think the pins just need moving about, to get that charging again.

Hi Sebastian,
My only recommendation here is try to buy a new pair of hands or put carpet
all over the house >.<

Alex,
Thanks for that, it seems in the very distant past I remember "stacking
of plates" and OSI 7 layers!!
Hope it was useful to other "lurkers" as well as it was for me.
If you are at the KT I'll buy you a drink!
