Also, need to bear in mind that 25-30 years ago, laptops were 10x more expensive than today.

For my postdoc in 1995, my industry sponsor bought me a then top-of-the range Dell Latitude XP with 100MHz 80486, integrated 80487 coprocessor and 32MB RAM for radar signal processing research.

In Australia at the time, it cost A$10,000, as much as my car.

Even the 24MB RAM upgrade from 8 to 32MB cost USD1,200 ($2,500) in today's money. Which puts current complaints about the soaring cost of RAM into perspective!
