Cause putting work off makes me happy (for the time being anyway) :)

But seriously..
I think it depends on what you're coding. For example web dev I usually find better to be in a fairly quiet environment with a desk and a large monitor. While command line apps in C is fine on a laptop on the sofa.

Hmm.. is there a need to give out laptops to all children at a school?
And do you need to get students to follow CIPA policies whilst they're at home?

I think if a school is giving all it's students a laptop I'd find it to be silly to block stuff as there will always be kids that will try to get past it and criminalize themselves.
I would've thought the biggest concern was getting malware on the computers.

If laptops were provided on a weekly/monthly rental basis and like school calculator and were wiped after being borrowed it would seem like a more interesting idea. The students could then be given pendrives to store the data. It'll be much cheaper than buying everyone a laptop and it'll solve the issue of giving students equal access to tools.

Unless the school is also going to provide internet access at home then I don't see the issue of letting them use it as they please whilst at home.

what about all the slaves^H^H^H^H^H^H workers at EA? :)
