Hello Jack, welcome to Sevenforums!
Touchscreen is useful, and fun. It is by no means neccessary, however. Windows has a standard driver
, but for a touchscreen, you will want to look up the driver on the monitor's manufacturer's website. There are 2 different drivers
- 64 and 32 bit. Make sure you get the right one according to your system.
If I were to use touchscreen, it would be because of application(s) that require it, or are easier to use because of it.
