Today marks the launch of the latest entrant to the next-gen console race: Sony's PlayStation 4. A number of reviews for the system have already gone up, but many outlets are waiting for next Friday's Xbox One launch before passing final judgment. With regard to the PS4's hardware and UI, Digital Foundry praises the DualShock 4 controller design and the improvements to background downloading, while worrying about fan noise in warmer environments. iFixit provides a step-by-step teardown of the device, giving it an 8/10 repairability score. Ars has many good things to say, but many bad things as well: "The PlayStation 4 has an excellent controller, decently powerful hardware, some intriguing, well-executed new features, and an interface that shows belated acknowledgment of some of Sony's most user-unfriendly past designs. It also has a lot of features that are half-assed, missing, or downright bewildering at this point." Polygon's review is more visually oriented, filled with pictures, videos, and drawings. They conclude, "[T]he PlayStation 4's focus on gaming — and only gaming — is undermined by a distinct lack of compelling software. That failing is sure to improve — better games and more of them will appear on the PlayStation 4 — but right now, this is a game console without a game to recommend it." Eurogamer's coverage includes has a round-up of launch title reviews and gameplay videos. IGN has coverage of the roughly 0.4% of PS4s that arrive broken out of the box, and Kotaku explains how they fixed theirs.
