I have to say I am really enjoying Windows 7 Ultimate. Since I switched my Dell 2100 from Ubuntu to this latest offering from Microsoft, I have been thoroughly pleased. Its clean, light, with just enough candy to make the experience not so bland. Maybe its a commentary or maybe not but I have to say that I have barely used my OSX hackbook since the switch. Chalk it up to ease of use with the touch screen on the 2100 and larger keyboard OR to the OS change I am not sure. Either way I am poking at this iteration of Win7 and time will tell. I do have to say that the way it worked with the other Vista (soon to be Win7) machine was very fluid and simple as far as sharing content over the network. Well played Microsoft… now what is your end game? I need an answer for the iPad…
