Points positifs
Points négatifs
Le nouveau Yoga 920 est le meilleur des Yoga de la série 900 jusqu’à aujourd’hui, et il est bien plus qu’une mise à jour matérielle. Les performances ont certainement été améliorées grâce au nouveau CPU quatre cœurs et au SSD NVMe rapide, mais Lenovo a amélioré d’autres domaines : le nouveau convertible est maintenant équipé de 2 Thunderbolt 3, d’un meilleur emplacement pour la webcam, d’un clavier modifié, il permet pour la première fois l’utilisation d’un stylet actif, et possède une meilleure autonomie. Lenovo a assurément pris au sérieux les retours utilisateur, et c’est agréable à voir.
Le châssis en aluminium est réussi, et plutôt robuste, et la charnière est toujours aussi séduisante. L’écran pourrait être un petit peu plus lumineux, et le contraste et l’échelle de gris un peu meilleurs. Il y a aussi la question de la taille : la Yoga est toujours l’un des plus gros convertibles disponibles, ce qui ne facilite pas sa prise en main en mode tablette. Néanmoins l’on peut apprécier la taille d’écran un peu plus élevée que la moyenne. L’absence du "Lift’n Lock" pour le clavier, du style du ThinkPad Yoga, laisse les touchess exposées, il faudra donc y faire attention. Le throttling en cas de fortes sollicitations réduit un peu les grosses performances des cœurs supplémentaires, mais la puissance globale est malgré tout supérieure à avant, donc ce n’est pas un gros inconvénient. Avantage supplémentaire : le sifflement gênant que nous avions sur le Yoga 910 n’est plus de la partie.
Le Yoga 920 est un convertible très bien conçu. Ceux qui pensent acheter un convertible du style du HP Spectre x360 ou du Dell XPS 13 devraient très certainement jeter un œil au Yoga un peu plus grand.
