Pros: This trackball is extremely comfortable to use, and allows a great degree of precision in use. The extra two buttons come in handy in many situations, especially in gaming where they can be programmed to perform specific actions, while still maintaining the ergonomic design.

Cons: After a few years the scroll wheel will wear out and begin to behave erratically. If it weren't for this I would have given this product four eggs.

Overall Review: I have bought three of these trackballs, replacing the old one every time the scroll wheel begins to wear out. Although each time I have gotten the trackball at half price (approx $50) if the trackball were to totally cease to function, I would be willing to pay full price for it, as since using the the RSI in my right hand has ceased to be a problem for me.

Pros: Two onboard nics, decent onboard sound, board seems to be durable so far.

Cons: Not a very good board for Linux. I had problems with the NICs when using Debian Squeeze, and on both Debian and Fedora 15 the sound card doesn't output to the correct jacks for my 5.1 speakers. The biggest Linux problem is the IRQ #17 error that comes up after a while, after which the system becomes to slow to use, this happened on Fedora and Debian (I worked around it by adding noirqdebug to the boot options, but this seems to prevent the computer from suspending correctly). Due to the fact that I have two 6000 series Radeon cards, I cannot access any of the PCI slots. The graphical UEFI is very irritating. I find it completely unnecessary, and hard to use. The wake on alarm option isn't very clear, specifically on setting the date. I figured out that you can leave it at 0 to get an alarm every day. Could not get my 2133 ram to get to 2133, had to leave it clocked slower.

Overall Review: This board was supposed to have a $30 rebate on it. I mailed in all the required items (including the UPC code and a copy of said UPC) but eventually I received an email from MSI stating that I did not send either the UPC or its copy in. I emailed their customer service email provided, but over two weeks later have not heard from them, nor have I heard from Newegg, who I requested contact MSI on my behalf. I recognize that at this point I am unlikely to get my rebate - bad enough given that I am on a college student's budget - but what really bugs me is the TOTAL lack of response on the issue from MSI.
