After using the Samsung Chromebook for about a week, I have determined that standard users will be alright with the browser-only computing experience; however power users and system administrators like us would only be hindered.
First thing I wanted to do was to find the desktop; which does not exist. I make very heavy use of virtual desktop on my workstation and being limited to a finite number of tabs bothers me on some level. I also had to lower the security on my wireless network to get the chromebook to work. I normally have my wireless AP set to use AES encryption with a pass-phrase but the chromebook would never pickup an IP address. To be fair my first generation Apple iPad also would not work with DHCP but worked fine with a static assignment.
Second, I have the chromebook sitting next to my Dell Vostro 1500 running Microsoft Windows XP. The Dell was powered off when I first powered on the chromebook and it received an IP. I used it for a while then logged off and opened the Vostro, which received an IP and worked. then I started having issues where Windows would say it could not retrieve a valid lease. After much nashing of teeth and hair pulling, I realized that both devices had the same IP address. It appears to me the chromebook will never give up its IP address once it associates with a network. No matter how long I leave it off, whenever it comes on it will take the same IP it has had since day one. That does not explain why my Windows box gives an error, but it could be that my wireless AP is just being stubborn and only giving out one IP address even though I have configured it to give out more.
If I get a chance in the next week I want to enable developer mode and boot a Linux distribution with a full desktop.
