When it comes to portable computing, there have been enormous changes in the last 20 years. These two old laptops reveal just how far we've advanced.

The first laptop shown in the video is a Dell Inspiron 5100. For a laptop that's over 10 years old, it's actually a decent computer. This particular computer touts the Pentium 4 2.4GHz processor, over 300MB RAM and a 40 GB hard drive.

The second laptop is a Panasonic CF-V121P Toughbook. This 'speed demon' has an Intel 486SX 33MHz processor, around 4MB RAM and a 200MB hard drive. That's incredibly archaic compared to modern electronics.

Here's something that may shock you. The vintage Panasonic computer had a list price of almost $5,000 in 1994. That's nearly $4,000 more than the Dell. Price is definitely something else that's changed significantly in the world of laptop computing.
