Thank you. By the way, it's "Ph.D.", not "PH.D.", which I would presume someone who has earned one would know.
Choose your time if you like. For now, you can still buy laptops with many high-performance replaceable and upgrade-able components. They may weigh 8 lbs and have 3 hours of battery life even if you aren't playing Doom, though. But come back in a few years and tell us how many new laptops are upgrade-able at all. This isn't an Apple trend, it's an industry trend. The laggards just haven't realized it yet.
