Higher end Chromebooks tend to have poor specs for what you get compared to Windows laptops. Mainly due to demand. There is low demand so few are made. Windows laptops will get you the best deal for your budget.
All-in-Ones are similarly overpriced for what you get. Anything under $800 is going to have horrible specs. At least anything I found was horrible. You can get touch screen monitors for regular desktops. But the price of the touchscreen and webcam will eat in to your budget. Although you can get a much higher quality webcam and microphone this way. Which honestly if you want to be getting a better webcast. You should be using an external camera and microphone. Regardless of what computer you buy.
Touchscreen laptops have fallen out of favor. They add to the cost and most people don't use the touchscreen option. You will have fewer options within your budget. There are a few to be had though. This Lenovo is slightly above your budget. But it is a killer deal even compared to non-touch laptops. You'll have to act fast though. When BHPhoto has one of these deals. They are usually clearing stock. Once it is gone. It is gone. Well worth going slightly over budget.
