Er..I meant what I wrote , except the bit about the other model. That was a reference to the Samsung G9 and its ability to use two different sources as video inputs.I love this!
I thought that your original post on this was a typo and you really meant that you're two friends had one each. I love it that you've turned the tables on me and you meant exactly what you wrote!
* Purchasing power *
It's rare to find couples with two of the exact same laptop ,screen,phone as inevitably one would borrow the other's laptop. Also when people spend £€$ , they prefer buying two different things..I think. Many people feel products are an extension of them/ their personality. So couples want to maintain their individuality .
Now about buying two of the same thing ...
Around August 2003 , I bought two identical hard drives from a retail shop . Two years later one failed on a Monday and the other had issues two weeks later :-( Lost a months worth of photos. Both were from the same batch. If I order/use multiple hard drives now , I try to buy them from two different suppliers. Generally only use Seagate and Western Digital .
