Five pounds is nothing compared to the many many books I carried to class in high school (which was easily close to around 15 pounds). I think I'll manage.
Also, while building it (still haven't ordered it yet, but I've got the page all set up), I noticed it comes with a printer (but no USB cable to connect it to the laptop). I have no need for a printer, as I can just as easily send my documents and such to my email account and print them off on the desktops. So, I unchecked the printer, and it took about 50 dollars off of the original cost. I replaced that with a RAM upgrade (3GB instead of 2GB). Sounds like a pretty sweet deal if you ask me. <3
