I have been using PCs/notebook for a pretty long time.
When I was in school (in the 1980s), to transfer files between two PCs, I had to copy the file onto a floppy drive, then use the other PC to read the floppy drive.
That was obviously a major pain if there are a lot of files and the files are too big to fit onto a floppy.
Luckily, later in the workplace (around 1990s), we could use laplink cables to connect between 2 PCs and transfer files between them. Networking in the office at that time was still not common and the laplink cables were connected to some port (I forgot whether they were serial or parallel port)
Then networking became more common and we can just share filles between computer over a network. And if we were somewhere without a network, we had several alternatives:
1. the USB thumb drive which though smaller than the floppy had bigger capacity.
2. infra red - my notebook in the early 2000s had a infra red port that I could point to another notebook also with an infra red port and both of us could transfer files. It was slow and there must be a direct line of sight between the 2 infra red points.
My next notebook after the infra red notebook came with Bluetooth but not infra red.
With Bluetooth, it was slightly faster and I could share with several Bluetooth notebooks at once.
The next evolution in sharing files ? Intel just came up with My WiFi technology.

Last week, we introduced My WiFi technology as an option on the Dell Studio 15, Studio 17 and the Studio XPS 16 laptops to customers around the world.
