Notes on the ThinkPad Edge 13 AMD Version:

Previously Lenovo offered a ThinkPad Edge 13 AMD version with a Turion Dual-Core L625, which is no longer available.  Perhaps because the Turion L625 was a bit underwhelming in battery life when compared to the Core2 Duo ULV version, but the CPU was a decent performer in terms of speed, especially as it was paired with a Radeon HD 3200, a step up from the Core2 Duo's GMA 3150 integrated graphics.  With the Radeon HD 3200, you'll have HD playback capability, and you'll even be able to play moderate level of games (think pre-2007 games).
