I'm thinking about getting a new Logitech MX500 (I think that's the model number) laser-based mouse. It's supposed to a lot more accurate than regular optical based mice, and it reportedly doesn't have any of the glitchy problems optical mice have with some slick, shiny surfaces.
quote: Steve Kraus Compared to work DSL which is an "always on" type the home DSL is a PPPoE connection (not sure if that matters) and has been fairly reliable. Connection was solid when I plugged back into it directly by-passing the router. So something is up there but no way to tell if it's just crappy software or a virus.
Steve, I could be reading this wrong, but are you saying you're connecting to your DSL line with the router and then just doing it with the computer straight? If so, I'm not sure how you're managing that unless you have a fixed IP or something like that.
My SBC DSL account requires one or the other of two things. If you're going to run the DSL modem's network line straight into the PC, then the Enternet 300 software or some kind of PPPoE software has to be used to gain a connection. But if you're running your connection through a router, like me, you don't install any of that software on the PC at all. The PPPoE settings, account info, etc. are all entered into the Cable/DSL router. I was told if you're using a router and have Enternet300 installed it will cause all kinds of hell.
Frankly, I'm much happier to not have any of that software installed on my machine. A bunch of it is just spammage shit --especially all that junk that companies like AOL and Earthlink stick on machines. Those guys make their software just hog up a user's computer. To hell with that!

Some notes in no particular order.
Daryl is absolutely correct; compared to all previous home versions of Windows, XP is a massive advance in reliability and stability. Its unfortunate that you are not experiencing that benefit, but you will get there. Its true; folks can argue over whether SP2 is a XP killer, or activation is evil, but those side arguments do not alter the underlying fact that XP is the best windows to date, in all sorts of ways.
DSL - PPPoE is the usual underlying connection mechanism of DSL connections. In the general case, DSL is DSL. The only difference between always on and dial on demand is how you choose to run your end of the link.
If you have a DSL modem, then from Windows point of view, its just like a regular dial-up modem, but it works a bit quicker. It has all the same Windows settings that a regular modem has, and the normal default setting is that it "dials up" when you open IE, or some other application that wants internet connectivity.
If you use an external router, then everything changes. From the perspective of the Windows PC, you have a permanently connected ethernet (or USB) connection, just like you were on a LAN in an office with thousands of PCs. Whether you are always on or dial on demand is set in the router. The routers I am familiar with have a checkbox on their web configuration screen, like this:

On this router, if you dont tick always on, then the router will drop the connection after a configured period of inactivity.
Although there is a school of thought that says you can use a software firewall to protect machines, I'm a hardware man myself, and think you should always have an external firewall whern you have an internet connection. Although I have no experience of the product you have, and the thought of MS making a firewall fills me with dread. Frying pans and fires spring to mind.
It is a truism that Network Address Translation (NAT) as practiced by just about every el-cheapo DSL router (and their expensive bretheren) is the single greatest thing that has happened to improve security of windows PCs, as long as it isn't configured to allow random incoming connections. Stick a router in the way of a DSL connection, and everyone benefits.
It is a simple fact that having a Windows/XP machine connected directly to the internet is scarily dangerous. Being charitable about it, Windows/XP is a big piece of software, and it has lots of holes in it. There are twats out there who like to exploit these vulnerabilities, and it turns out that non-currently patched non-proper-firewalled DSL connected machines are in abundant supply, and can be used to make money for the bad people. A non-currently patched non-proper-firewalled DSL connected machines is not only a pain to its owner, but a pain to everyone out there on the internet, as such machines are reconfigured from being servants of their owners to servents of bad people. IT professions (amongst others) tend to be quite impolite about the owners of such machines.
If a machine as above is left on the 'net for a few hours, it will likely be discovered and hijacked. And then used for abusive purposes. Yes, thats where most of the spam comes these days, from DSL connected machines with naive owners.
Just as an example, a random line out of my spam wall: Honeypot <burton@tex.com> caught <mmgtdyicpryn@163.com> at 68.89.189.244, and that IP address is... adsl-68-89-189-244.dsl.hstntx.swbell.net. Just another DSL user with an unprotected machine.
And if you've still got self-closing task manager and msconfig windows, you still have a virus or trojan.

The difference is - there isn't one.
Unless your PC gets compromised...
Or there are ports exposed "around" the software protections, which is possible given the way that XPs IP stack is (cleverly) constructed, making for easy plug-ins, allowing for on the fly filtering, packet modifying and monitoring.
Although the el-cheapo routers may not be perfect, and there have been many reports of vulnerabilities, in practice they are still useful enough to protect the PC(s) behind it. So my choice, and advice, would be to spend the few extra bucks over zone alarm to get any hardware router.
