The entire point is that pretty much any other (read: non-Apple) laptop/desktop you buy nowadays is going to come with at least 500 GB, and generally 1 TB nowadays.
No need to get up in arms and whine that Apple is doing everything just right for your tastes.
edit: I obviously wasn't referring to 1 TB SSDs. The parent's comment said that 128 GB is pretty paltry for storage capacity nowadays, as the thread is concerning the rate of growth of SSDs.
