I don't have sales numbers, but yeah, I bet the midpoint in prices for laptop sales in the USA is below $500. And by the way, Apple's laptops don't sell well. They have less than 10% of the market. They are hugely profitable, but don't confuse that with popularity. They are broadly DESIRED but rarely, in the big picture, purchased.
Average non Apple laptop as of January cost $456. So yeah, most laptops cost well under $499.
Bullshit. They're all the best-selling laptops in their price range. The Macbook Air is the best selling ultraportable out there. So yes, they 'sell well'. Just because Apple doesn't target anything under $999, so has basically given that market away, that doesn't take away from the sales of their current machines. Rarely purchased? I know this is anecdotal, but I see Macbooks all the time in every kind of setting, and they're selling better and better each quarter. Sure they're no iPads/iPhones in terms of popularity, but then again nothing is. So tell me, how much profit is being made on these dirt cheap laptops you're referring to? Are they made by the same companies who want to leave the PC industry? I've never seen a sub-$500 laptop that wasn't a piece of shit, nor does one exist.
