I would suggest the ThinkPad X120e! Check it out on amazon:http://www.amazon.com/ThinkPad-X120e-05962RU-Notebook-1-6GHz/dp/B004PILTA8
AMD Fusion E-350 Dual-Core 1.60GHz Processor
AMD Radeon HD 6310 Graphics Card
Genuine Windows 7 Professional 64bit
Let me preface this review by saying that I have only had the x120e for about 24 hours. The short of it, is that the x120e is a fantastic laptop that should not even be mentioned when discussing or comparing, "netbooks." The x120e has handled everything I have thrown at it so far from playing back 1080p .mts videos from my Panasonic camcorder (although I had to download the Shark007 codec package, use google to find it), having 6+ firefox tabs open along side of VLC playing mp3s, and working in Microsoft word and excel at the same time. Many have even been gaming on it with Modern Warfare 2 running in the 20 fps range. Steam games like team fortress 2 run great on it. Do a search on youtube to check some of them out.
As others have mentioned it might be worth upgrading the hard drive to an SSD, I might do that in a month or so, but a cheap upgrade is the ram. You can get an 8gm ram kit off amazon for $50.
And I will be honest, I am replacing a 13" Macbook air (mid 2010) that my friend wanted to buy off of me. The x120e does all I need it to do, I was even able to edit some audio in adobe audition 5.5!
Aesthetically, the x120e is a very sleek, although not flashy, machine. Yes, it is thicker than the air, by about 2.5 times, but it doesn't matter. The length and width are identical (except the batter sticks out a little).
Finally, it comes loaded with Windows 7 Pro which will be great for business folks. Windows 7 is really a great operating system and goes toe to toe with OSX.
