This week I found a great deal on refurbished Acer Aspire One netbooks with WXP. Obviously, I prefer and use Linux over Windows but for certain purposes such as tethering and our oldest son needing an XP platform while away at college fits my needs. With all the hoopla of Windows 7 coming out I believe XP to be their best OS to date.
XP is great at PnP, USB support, and with the latest service pack is actually useable. But I will miss the almost instant on/off that Linux gives me but that's OK since I have four netbooks and and only half of them run XP.
The most incredible part is that I found these on TigerDirect for around $200 each for specs such as the ubiquitious Intel Atom proc, 120GB HD and 1GB RAM. That's pretty good horsepower considering I use to configure servers when I first started out with Pentium 180 Pro procs, 256MB RAM, and a single 2.5GB SCSi hard drive.
Moore's Law is alive and well....
