The laptop that I have on loan from one client is similar - it is so small/slow that I have a tough time running the latest PCB design tools on it, but I've managed to get it to work even when the client's IT department couldn't. My own laptops are much bigger, but the client has specific requirements about network access and access control software, so I use this PC when connected to their networks.

Besides, they say that it's not the size of a man's hard drive, but what can he do with it, that counts.. ;-)
