What old models? As far as I know there aren't any older MacBooks that support more than 16GB of RAM either. If you're going to compare to desktops, start with the iMac, which is "only" a year old at this point, unlike the Mac Pro which is several :(. The iMac with 5K display starts at $1,800 and is configurable to 32GB RAM, while the MacBook Pro 15" starts at $2,400, and then you probably want an external display too. (That doesn't include the rather high price of actually configuring the iMac for 32GB, but its RAM is [still] user-upgradeable, so better to buy it somewhere else.) Actually, considering that the Mac Pro starts at $3,000, which is not that much more than $2,400, I'm not sure why you think the price puts it out of range... But I definitely understand why you'd want it in a laptop.
