Sony VAIO TX670P/B (Pentium M 753 1.2 GHz, 1 GB RAM, 60 GB HDD)

Depending on where you buy it, Sony backs the VAIO VGN-TX670P with either its new business-focused VAIO Care program (read about details here) or its industry-standard consumer warranty: one year of free service (including free shipping both ways) and 24/7 toll-free telephone tech support; after the year expires, support calls cost $20 per incident. Sony offers an array of warranty extensions; a three-year plan with onsite service costs $250. The company's Web site provides a good knowledge base and e-mail support from Sony technicians.
