For the most part, Windows 7 beta works well on my new LG X110 netbook computer. These are some areas that still need fixing:
Accessing files on the netbook from other computers works poorly. Windows 7 has a new concept of the "Home Group," which allows any computer in the group to access any other's files. Problem is, Home Group works only for other computers running Windows 7. In the meantime, I continue to use a USB drive to copy files to and from the Windows 7-based computer, because Microsoft doesn't want me accessing my data on my computers.
The unzip function in WIndows 7 is as painfully slow as in Vista. I began to unzip a 1.5GB .zip file, and Windows 7 estimated it would take about an hour. Using my USB key, I copied the 7zip installation file onto the X110, and then ran it on the monster .zip file: job done in under 6 minutes. The free 7zip software is 10x faster than the utility that's part of an operating system Microsoft charges for.
Other problems I am guessing will be fixed before release, such as Windows 7 forgetting settings. For instance, I turn off all sounds, and Windows 7 turns sounds back on with the next reboot.
Next test: does AutoCAD run on a 1GB netbook under Windows 7?
