>Get a proper laptop with fullsize keys and a large enough screen to work on.

No laptop in existence has a keyboard big enough for me. The smallest external keyboards I've used are probably larger than the largest laptop keyboards.

It's not about the size of the keys. It's about the location with respect to your shoulders. Having to angle your arms inwards is not a good idea.

Same for screen. If you're looking downwards, it's bad for your neck. Which is why I always use an external monitor.
