Before we start answering existential questions, though, let’s quickly recap what’s new with the iPad Air. It still starts at $599 for an 11-inch version with 128GB of storage; the 13-inch models starts at $799. The one I tested came in an extremely light purple color with 1TB of storage and 5G connectivity and costs $1,249. Seriously Apple, don’t be afraid of putting a little more saturation in these colors next time! As mentioned, the iPad Air now has a more powerful M4 chip as well as 50 percent more system memory (12GB, up from 8GB on last year’s model). If you’re coming from an iPad older than the 2024 model, you’ll likely notice solid performance gains, and the M4 is so performant that I imagine this iPad will be more than powerful enough for years to come.
