The installed base is the asset, and the phone is the renewal

It helps to think of each phone sale less as a transaction and more as the renewal of a relationship. The relationship is where the durable revenue lives: the apps, subscriptions, storage and payments that follow the device.

Why the base compounds

Every active device is a point of distribution for services with very high margins. People rarely leave an ecosystem once their photos, messages and purchases live inside it, so the base grows even when hardware sales are flat.

That makes the hardware cycle matter less to the long-term value than it does to the next quarter.

What I'm watching

• Active device count, the real denominator
• Services revenue per device
• Regulatory pressure on the app store, the part of services most exposed

Where I stand

Long, on the installed base as an asset that keeps paying between upgrades. The hardware is how the relationship is renewed; the services are how it pays.

What would change my mind

Regulation that opens the app store to cheaper alternatives at scale. The base would survive it. The margin on the base would not look the same.
