The Lenovo ThinkPad X121e is a great laptop for someone looking for portability and not high performance.
The Asus Zenbook UX31 is a sharp-looking ultrabook with great specs that is severly let down by its poor touch pad and keyboard.
The Samsung Series 7 Chronos laptop is a great, not to mention cheaper, Windows alternative to the MacBook Pro.
The Dell Vostro V131 could be thinner and lighter, but still has a powerfull processor and great battery.
The Aspire S3 Ultrabook is perhaps one of the top Windows-based alternative to the MacBook Air if you are alright with a few cut-corners and less of a quality look/feel when compared to the best-selling Apple competitor.
The Samsung Series 9 is one of the lightest and thinnest Windows 7 computers around that still performs very well. Despite its high MSRP, this is one serious competitor to the MacBook Air.
The Lenovo IdeaPad Y570 makes a decent gaming laptop but is bulky, unattractive, and not very portable.
The Lenovo IdeaPad S205 is a well powered portable laptop selling at a good price
With an upgraded graphics card and processor the Envy (2011) should continue to be a top seller for HP.
The HP ProBook (Summer 2011) took a page out of Apple's design book and unfortunately cut corners while doing so. The ProBooks are still a step in the right direction for HP and are liked by many businesses as a Mid-Level option for workers.
