Generation: The iPad Air you're considering is the first generation model. Apple has released newer versions of the iPad Air since then, with the latest being the 5th generation released in 2022. Newer models will have faster processors, better cameras, and support for newer software features.

Storage capacity: 32GB is the lowest storage capacity available for the iPad Air. You may want to consider a model with more storage if you plan to store a lot of photos, videos, or apps.
