Per-gigabyte price is used a metric iPad purchase decision-making all throughout this article: https://www.imore.com/what-ipad-pro-storage-size-should-you-get To calculate this metric, Rene divides the entire price of the iPad to deduce the per-gigabyte value, which makes the base models look like terrible purchases in comparison, i.e. $10.15/GB for the 64 GB iPad Pro, compared to $1.85/GB for the 512 GB model. It also makes the 10.5" models look like much better value than the 12.9". Am I missing something? I cannot think of a single way in which this metric could possibly be relevant to anyone for anything, unless you are looking to use an iPad only as a storage device, in which case a thumb drive would be a much better choice. Not only does it seem to be an entirely useless number to base a decision on, it also appears to me to be completely misleading. If you would instead subtract the base model storage (64 GB) from the higher tiers (256 GB and 512 GB respectively) and divide the price difference ($100 and $300 respectively) by the storage difference you would find that for both pro models the per-gigabyte upgrade price is $0.52 for 256 GB and $0.67 for 512 GB. (The upgrade price for the 9.7" to the 128 GB model is $1.04, but as that is the only possible storage upgrade there is no comparison to be made.) So, from a storage perspective the 256 GB models are better value than the 512 GB, and by extrapolation it is probably safe to assume that the 64 GB models are the best value. Of course, the article does mention other aspects to take into consideration, but I wonder if the article wouldn't be much better if the upgrade storage divided by the upgrade price had been used instead, or if the per-gigabyte price had been excluded altogether. Thoughts?
