So, this is my post number 1.000! It took me almost 10 years but I managed to get here :). So I thought of placing a summary of the reviews the Steam Deck got up until now, so this important milestone can generate some further buzz. Please note that unfortunately I don't have a Steam Deck yet, so I rely heavily on the lovely people around our community, like our dear @Conina, for hands-one experiences and impressions.
That said, here we go:
The Metacritic reception is fairly good, even though there is no general score.

Verge is fairly critical, even though having some nice things to say about it:

IGN seems to like it too, but not much better grade:

Kotaku presents some nice points, mainly the "sofa test":

Many video reviews have been posted in previous pages of this here thread, so I won't repeat that material.
I hope you enjoy this 1.000 post of mine. Let's celebrate.
