The x41 had a basic performance problem - they switched to the smaller, iPod-like hard drives, as compared to the regular laptop hard drives that the X31 had. This was unfortunate - when I had the X31, I immediately replaced the stock drive with a 7200RPM drive, and the X31 screamed for years. Then, I got the X41, found out that the same surgery is unavailable, and promptly got rid of it.
