Hello Tom,
I found this very interesting and did some research to enlighten me further.
I do a lot of video shows with PTE using a Windows laptop and a projector in large venues.
The laptop although only a 15 in version can be a problem for space and heat issues.
I also use an external keyboard with Bluetooth so I can move about.
The laptop has 16 gb ram and a decent video card. The videos run smoothly.
I like the size of 5 inches, as it would not take up much space.
I might consider using something like this as the laptop gets older.
Do you think this may be an alternative?
Take care,
Kieron
