Google Trends is likely one of the best indicators to answer such questions:

Sysmetrix still works to some degree but there is a lot outdated about it that will never receive updates. Last I used it the weather was still working but sysmetrix weather was never great. Only supports 1 processor and all the motherboard options do not work. Email is limited too. Skinning it is easy but having to use a bitmap for the background sucks. It is good software but without updates I won't be using it any longer. I now use xwidget because it offers more options. 

His name is Nick Decker and yes he has abandoned it. I actually was the one who got him to do the last update for the weather. I contacted him again offering to pay him to update it but he has lost interest in the program plus he has a lot of other projects on the go.

I have skinned several xwidgets now so if you ever need help let me know. I also put together a beginner guide for skinning it that I can pass on to you. It just gets you going with the basics.

Are you kidding me Uvah. There is a huge gallery at deviant art, mind you have to scroll through a lot to weed out the crap but there are some good widgets there.

You might like the actual xwidget site gallery better because it has less of the crappy skins. http://www.kuyuapp.com/xwidget/

PM me your email addy and I will send you the guide.

I just sent it Ross.

"If I can get the skinning bug back, I plan to try. Wish WC had a gallery for it."

Well with sysmetrix and desktopx going the way of the dodo there should be an alternative. There is a rainmeter gallery but not everyone uses rainmeter and it is harder to skin than xwidget, (well not really but more code involved). I don't know why there could not be a xwidget gallery here. It would only serve to bring more people to the site. Varity is a good thing. 

You should have an Xwidget bar running. It hides off screen at the bottom, I believe. It houses all your widgets. Or, I think you can just click the systray icon.

By the way if you want to get to the actual xwidget gallery at deviantart do not type xwidget in the search box to get to it. When you use the search you get everything related to xwidget including screenshots and a bunch of other junk. The best and easiest way is to find a widget you like and save it in your favorites. When you open it you will see in the title of the widget the location which looks like this,  Customization / Skins & Themes / System Monitoring / XWidget. just click on the word XWidget and it will open the actual gallery. once you have the gallery page you can bookmark it, save it in your favorites or create a shortcut. Once you are in the gallery you can use the white search box to search for specific widgets such as weather widgets. Just enter weather in the search box (white search box and not the search box beside the deviantart name.)

I have some XWidgets that I made in my gallery. http://kjc66.deviantart.com/gallery/

Ross you will not get the bar that way. You need to double click the XWidget icon in the tray to get the bottom bar to popup.

Oh......

Ok......

I got it.......

I didn't know that. Lol
