I'd say give, give.
Laptop will give you mobile central place of work, desktop will be say central place of work. Work from mobile or work from not. Be all i can say.
Laptop will give a places to work at your desktop can't, but your desktop will probably give one place to work.
In terms of computing, at some times for the interest there is really only a small difference sometimes, but alot of differences many times.
If you don't need the differences, don't go for them. They are nice probably of differences of course, but actual use will vary. For like computer hardware anyways, sorry. My bad.
And in terms of word processing (can't spell). If you are concerned with the fact of like paper and you can just drop typing in really fast, you might lose the bulk of the paper. Paper to say anyways.
Otherwise its like trying to do more with say "paperwork". Which is probably fine of course, at time sometimes to say of the idea, some use of interest might find its place otherwise its almost a "thrown" rush for the interest. But still about what you can work with though too, so don't forget that one.
Price, price varies horribly really sometimes, but then not enough for much thought though.
So, who knows. I don't much obviously. But thats probably what makes some thoughts worth something. Yes?
But laptops aren't cheap usually, and if they are, probably are easy to lose; rather can believe it or not: cause they are probably fairly heavy.
