Do you feel as if your palmtop is a one trick pony now. Can your palmtop do all this? They can! Either through a web browser or a remote desktop viewer. having a local web server, you can install applications that will run without the internet but do work with the local intranet.There is even software that will emulate a computer desktop.
Most palmtops have terminal server clients. With the remote desktop viewer you can access another working computer on the network be it Linux, OS/x, or even Mswindows. You start the rdp (remote desktop protocol viewer) software and then enter the hostname address.
Of you will need to set up a login and password on the host for if nothing else minimal security restrictions.
Once your in, you can use the hosts as if that operating system was on your palmtop! Here we have access a remote Linux computer. You can even get a remote Raspberry Pi desktop, so the RPi does not need a monitor.
