Thanks for the explanation, Andy. I do understand the points about restructuring the reviews, but at least the prices should be displayed, as if there were too different prices, then when opening the individual reviews and checking the purchase dates, that could explain why the price differences. I would easily sacrifice the star ratings for two little text items, price and date of purchase.
Purchase dates can also set a timeline for a certain product that might have had its hardware revised, so the review is accurate for that time and not later (or before, if it's the case), due to different hardware specs of the same piece of equipment.
Price is also tied to the same line of thought, as both during a certain period of time or version 2 of gear X cost more (or less) due to having different specs.
I just think it would make things clearer without forcing people to open individual reviews in order to get the same info. The set of stars is big and would make loading slower, but a few characters not exactly.
Anyway, I'm just saying my 2 cents, wishing things to be different than they are now.
