Wasn't the EU single market supposed to fix that?

The EU single market has no positive or negative effect here as it's a private purchase not subject to any regulations.

I am free to buy and sell to and from any country in the world, the issues is not everyone is willing to deal and pay for international shipping which ends up quite high for a cheap SFF tower system.

> not everyone is willing to deal and pay for international shipping

In principle, shouldn't one of the consequences of the EU project be that intra-EU shipping rates should, for the same distance, be identical between within the same country and between EU countries? (Of course, I realise that outcome may not yet have actually been achieved in practice.)

In theory. In practice roads between counties are not as good so cost goes up.

One of the EU projects is trying to improve the transport links (including road network) between EU countries – https://ec.europa.eu/transport/themes/infrastructure/ten-t_e...

One would hope that if they are successful in improving those transport links, shipping costs will reduce as a result.

Somewhat. Population also tends to be centered around the country so it even if transportation is better people still have their lives setup such that practically shipping in their country is cheaper.

The EU is a single market, but that doesn't stop all the countries having different languages and consequentely different keyboard layouts. So you are looking in your country, perhaps in a second, which shares your keyboard layout.

About laptops, I mostly agree. (While the wrong keyboard layout is something you could learn to live with or workaround, in practice it may well be too unpleasant to be worth it.)

For desktops, it shouldn't really matter. One quite likely already has a spare USB keyboard with the right layout, and if one doesn't, it shouldn't cost much to buy one (whether new or second-hand).

Small market, low demand. Low demand, low prices

Except the reality says otherwise.

Big markets like US, UK and Germany have low prices on consumer products and in small markets like Austria and BeNeLux countries consumer products cost more.
