This is very easy to do and very useful for personal use. However if you plan on building a webpage that will have lots of traffic and/or lots of large multimedia files you would probably be better colo’ing or finding a friend who can give you a deal on some good cheap hosting or something like that as most ISP’s don’t offer much in the way of upstream bandwidth.
However if you fall into the catagory of ‘this would be very useful!’ Here are some ideas.
You will need a good router (linksys BEFSR41 or WRT54G are a great buy for a wired/wireless solution) for internet sharing between your main pc and your webserver, and it is a good idea to set up a DMZ for your webserver.
Next you are going to need a computer. Maybe you got a new one recently and still have your old one, maybe there’s one in the attic somewhere, maybe you will have to find some kind of discount computer store. cals in vancouver is great for this kind of thing. You don’t need that much power or anything (depending of course on what you plan to do with it, but in general for a home based test bed you won’t need much more than a 500mhz with 256MB of ram, 20gig hdd, and a nic and you are all set. Of course having a cd drive handy makes the install process much easier.
Once you have a computer you need to decide on an OS to run, if you have any experience with linux/unix it is a great way to go, very secure and very customizable! If you don’t, don’t fret. There are many other ways to go. If you somehow happen to have a spare copy of windows (2000 or later preferably) you can install that and then install xampp and you will pretty much be set. I don’t actually have any experience with xampp but it seems to be pretty straight forward.
Yet another option (and I’m sure there are a few more like it) is called clarkconnect the home eddition is free and it is the easiest linux distribution I know of to set up and use. Follow the simple steps to install and then administrate it all through an easy to use web interface. You can even get a free dynamic dns address with it. (yourname).pointclark.net (or something like that, I forget what it is exactly now)
If you happen to have a few spare computers you can even set one up as a super powerful router that has many nice features.
After all of that it is up to you to do something fun with it!

Having a digital assistant has helped me out in many ways, it has helped me become more organized (mostly), remember appointments, find something to do on long bus rides, and so much more.
There are many questions you must ask yourself before you go out and impulse buy one of these things. Is portability most important to you? wi-fi? bluetooth? palm os or windows based? audio/video capabilitys? etc.
Next thing is lots of research. Learn as much as you possibly can about different devices and their advantages and/or shortcommings, make sure you make an educated decision so you end up getting something that you get lots of use out of instead of something that is cool for 2 days and then useless later on.
Personally I love my Palm Tungsten T|3. The only thing I could ask for on it would be better video playback capability and wi-fi, and the latter can be solved with a wi-fi sd card which is on my shopping list!
