I had a laptop awhile ago. It worked perfectly, but the only problem is that I think (this is when I bought mine, so things might have changed) that the graphics card is integrated, and I couldn't get better quality from my add-ons, and it started getting slow because I hadn't get a very good graphics card, and it was integrated, so then I switched to the computer I have now, which is brilliant. I have at least over 8 big programs and they work fine but mine isn't a laptop, and it's got the best video card around, and it's very expensive because it can hold so much memory, but it would be a waste of space and money if you're only going to put FSX onto it, so I'd recomend to try to find a decent laptop, that hopefully hasn't got an integrated video card so you can update if you need too.
