> For someone who allegedly doesn't understand that the recent $89bn gain on Apple stock is nice going. Luck perhaps

From an investor point of view, you can't categorize companies as one label. You can categorize companies as tags. This is because every perspective that allows you to give you an edge and make money in a fairly reliable manner is a valid perspective.

Apple can be seen as a consumer/physical product company. Warren knows a lot about consumer behavior and branding. If he finds from that perspective that Apple is underpriced, then he can still make a bet while having a limited understanding of the technology by simply saying: a laptop is a laptop, it allows you to do laptop things (i.e. they're interchangeable), but Apple has an amazing brand like Coca Cola.

Of course, this isn't fully true (e.g. Windows enables different things than Apple in some cases like gaming) but combining it with superior knowledge in branding, it's good enough to make a bet.
