Pros: Works great in Windows 7 64-bit. I use it with GIMP; GIMP recognized it immediately and it works fine. This is my first tablet, so I can't really compare it to others, but its tracking and pressure sensitivity is more precise than I am.

Cons: None

Pros: Works properly for standard serial transmissions; effectively the same as a USB-to-serial converter. Worked on Windows 7 with drivers from CD.

Cons: It outputs +/-5V, like USB-to-serial converters do, rather than the +/-12V that is standard for built-in PC serial ports. That means it didn't work with my device (a JDM programmer for PIC microcontrollers). For the price, I expected it to duplicate the full PC standard.

Overall Review: It will work fine if you're doing standard serial TX/RX, but don't buy it for older devices that rely on full use of the serial port specification. (I ended up just giving up on getting my device to work, and bought a newer equivalent. Not sure if the other PCI-to-serial cards on here would have worked better or not.)

Pros: Works well for the price. See usage tips below.

Cons: Without the drivers, Windows doesn't sense the pen tip pressure. But the Kanvus drivers don't support a multi-monitor setup (they map the pen to reach over the whole screen area, making it useless). However, with some searching I discovered that the drivers for the Genius "G-Pen F610" will also work with the Kanvus 106 (same chipset apparently), and the Genius drivers properly support binding to a single monitor, plus they support Windows 8. So I highly recommend using the Genius drivers.

Overall Review: The pen sensing gets unreliable when the battery gets low. So if you see bad sensing, change the pen battery.

Pros: Very good sound quality. And with WinXP, it's automatically recognized as a USB thumb drive, so you can just drag MP3's onto it. There's automatic sound equalization, so different MP3's play at the same volume.

Cons: Ear buds can fall out when running; I'm going to buy the wraparound kind.

Overall Review: I'm glad I went with this instead of an iPod. You don't need any software on your computer, and the interface on the MP3 player itself is good.

Pros: Very quiet with the included fan. With the computer case closed, you can hardly tell the computer is on. It's a huge improvement from my last processor, an Athlon 1.333GHz. Great performance in games, too.

Cons: None
