| The Bottom Line | The ThinkPad X61s provides excellent dual-core performance in a lightweight, compact package that's still comfortable to use. | If you're in the market for an affordable thin-and-light, the Asus UL30A-A1 provides great value and a solid Core 2 Duo CULV processor in an attractive package. | Toshiba's slick entry into the thin-and-light laptop world is timed for Windows 7, but if you're going to get one, make sure it's the dual-core T135-S1310, and not its single-core cousin. | |
