I bought a new notebook in August, and was torn between the Sony T350 and the Fujitsu 7010D. I wound up going with the Fujitsu, and I'm happy with my decision. The significant differences (at least where I am concerned) are that the Fujitsu has a fingerprint reader for security, and the optical drive can be hot-swapped for an extra battery (which I bought). The Sony has a built in EDGE modem, but that requires a subscription with Cingular and a fee of around $80 a month.
The notebooks are roughly similar in weight, size and price. I found that the Fujitsu had a marginally better keyboard, but the difference is small and idiosyncratic.
Reliability on the Fujitsu has been A+.
