I've got a USB one I can use for now which is fine. I have a desktop I can use.
School term starts in September so I'll definitely need one for teaching purposes. I just ordered the keyboard part from ebay for 20$. It'll take about 15 business days. I'm waiting for the back-to-school sale in August before I get a new laptop.
I backed up everything before I took it apart to have a look (just in case it didn't turn back on)
