Wacom UP710E Tablet PC Eraser Pen

Pros: Good gradient in sensitivity to pressure unlike some. Button fits your finger naturally. Works with the HP TM2 as a replacement as well if you need that.

Cons: Not two button.

Pros: Great Buy, Took a while to get used to but, A++ Will recommend any beginner/ Pro to purchase this.
Price is marvelous.

Cons: None So far

Pros: It works just like the originals. I have used these on IBM's, Fujitsu's, HP's, and Toshiba's. They will work on any tablet that uses WACOM technology.

Cons: Not a factory replacement... it won't fit into the slot on your tablet PC.

Pros: It's a pen. It has an eraser and a side button. I bought it as a replacement for the now-broken pen that came with my X61 Tablet PC, and have had no problems. It seems more durable than my original pen.

Cons: The color doesn't match my laptop. Other than that, none.

Other Thoughts: I'm using this pen under Arch Linux with linuxwacom 0.8.1-6, and have had no problems.

Pros: I have an Acer C200 tablet PC and the pen actually works a little better than the one that came with it. Works perfectly!

Cons: Does not have a pen clip attached so it doesn't fit in the slot on the tablet, I keep it in my laptop bag with the rest of the pens so this con is minor.

Pros: Works great with my Wacom-enabled Fujitsu T-3010 tablet/notebook. Should work perfectly with any other Wacom "Penabled" notebook.

Cons: Does not fit pen-holder on the side of my LCD, but that is due to Fujitsu's older design.

Other Thoughts: Make sure to update to Wacom's newest drivers, especially if pressure sensitivity is not working. Most (if not all) Penabled units support Pressure sensitivity, if you have the newest Wacom driver. Just go to wacom.com, under downloads and Tablet PC.
