Google hardware launches are never spec-fests. The search giant would rather just sit on the sideline while companies like Apple and Samsung battle it out on that front. In fact, numbers like screen resolution, processor speed and battery capacity were conspicuously absent from today’s presentation.

Instead, the company seems more content to have hardware serve the product’s software — it’s a strategy that certainly makes sense given the company’s background. That often means that products like the Pixel don’t offer major spec upgrades year over year, instead relying on breakthroughs in AI, ML and the like to take them to the next level.
