Keep it. I understand. Even if it wasn't your first.
To this day I regret selling my red game boy colour, but I learned from that mistake and when I had the opportunity to sell my pokemon games I didn't. I payed for them so they're mine, plus I like my pokemon game collection
Thanks guys I've decided I will do the swap but keep my desktop machine. In my original plan I was never going to get rid of it anyway.
My indecision on this was just plain silly
