I only have a desktop. I thought about getting office space from the chamber of commerce for 250 per month... and I can use their fridge to save money on food (Greek yogurt, Jimmy Dean sandwiches, and string cheese is all I need)...
Sell it. It's a paperweight for you right now. You can find a really nice open-box/used laptop for $300-400 that will allow you to work from anywhere. You can charge the laptop at a cafe or a library. $5 for coffee and you have a working space to take calls and work.
