Is it worth it to buy a 10 year old used iMac G5?

Hi there! I have the opportunity to buy an iMac G5 from work...it has outlived its usefulness for what we do, and hasn't been used in a few years (although it does work...I spent yesterday afternoon getting files off it and trying it out). My research tells me that it doesn't have an Intel processor and can't be updated beyond OS 10.4.11 (which is what it's running now). My current home computer is a Macbook Pro 15" from 2009...it runs Mavericks and I love it, but it is getting a little short on storage memory, and this iMac has plenty, plus a 20" display. For $200, I can have the iMac, and I'm envisioning keeping it as my email/Facebook/Netflix/Skype computer, and still have my Macbook to move around the house with me (I often like to take it to my living room, bedroom, dining room, whathaveyou), and for travel. Is it worth it, do you think? What sort of problems/issues will I encounter with a 10 year old iMac? Will it even run Skype and Netflix? Can you think of anything else cool that I can do with a $200 used iMac? Thanks in advance!
