Pros: Plug-and-play with no drivers necessary with Win XP SP2. Both the keyboard worked (I use a USB mouse) and the barcode reader that piggybacks onto the keyboard PS/2 jack work without incident.

Cons: I had a hard time putting the card in, physically, on my Lenovo. Probably more of a problem with the PC than the card.

Pros: This memory worked perfect out of the box, and has not yet failed after some months of moderate, daily use. Installation surfaced no issues, and it noticeably, and of course positively, affected the desktop. Also, at my time of purchasing, best price on NewEgg. Wonderful!

Cons: None.
