@OP : Unless you and your desktop have a huge distance between them, are you kidding me?
And no, if you're not gonna use it other than in your bed, it's absolutely not worth it. Really, a desktop and a laptop? How they are even remotely comparable? Only advantage of laptop is, it's portability, and if there's no use of that then it's like buying a F1 car and trying to drive it on normal roads.
I hate laptops to the guts, paid 120k, back in 2009, for some Alienware crap, then paid less than half for the desktop, and it's performance literally mocks the Alienware. Worst purchase I've ever made. Just couple of months ago I had three, sold two of them. Now I've only one, and that's just for MS Excel works when I need to visit my clients.
If you really need one, get the cheapest i3 available. Spending big money behind a laptop can't be any more meaningless, sorry I honestly don't care who agrees with me and who doesn't. For power users like me, it's simply a joke.
And remember, you asked for opinion, I provided mine, as others did above. Commenting here doesn't increase my bank balance, it's your money, you wanna make a wise decision or waste your money is simply up to you. But if you end up buying something expensive by then you might regret it.
