Je n'ai pas encore eu le temps de voir ses limites, mais pour l'instant il semble remplir le cahier des charges.
Seuls regrets (pour l’instant): vraiment trop peu de port usb (2), et un poids non negligeable (ce qui donne finalement un sentiment de robustesse). J'avais l'intention de repartitionner et d'installer fedora, mais pour l'instant je n'ai pas eu encore le temps et finalement Ubuntu ca marche 🙂)) ...
Merci encore pour votre aide dans le choix !
