When using my mages, I have used my laptop before. It wasn't anything special, but I do prefer playing on a desktop.
How many sessions (i.e., "mages")? What are your laptop's specs? Finally, does "wasn't anything special" mean acceptable if you were stuck without access to your desktop or poor enough that you'd not bother trying to multi-box?

Again, I'm trying to get a sense for portable options for when I'm not at my desktop.

Thanks!
