logmein.com
I use logmein.com. I find it to be a good service. I have no financial interest in the service, although as I write this I think I should sign up and be an affiliate.
I have a desktop and a laptop. Many are getting away from that combination and just working with a laptop, but I still have both.
When I go out on the road, I take my laptop. If I am working on the Internet, I just connect directly. But sometimes I want to access a program that is only on my desktop, like Photoshop.
Then I connect to the internet, sign on to logmein.com, and then link up with the desktop. I can use all the desktop products.
I am certainly aware that there are multiple products and services that do this, but logmein is my favorite, and for what I described, it is free.
The reason that it came to mind today is that the video card on my desktop died. I will put a new one in soon, but in the interim, I started the desktop and the laptop, and I am accessing the desktop through the Internet.
So I am sitting here using the desktop monitor and keyboard, but running through the Internet using the laptop. The laptop and the desktop are a few feet away, but I am sending the packets over the Internet.
Now I know of course there are other ways to connect, but this way was already set up, and so it was the most expedient to do.
It is surprisingly quick.
