My first five-megabyte hard drive cost $500. Look back a few years, Mr. Mossberg. My first five-megabyte hard drive cost $500.

Tempting as these light weight min-laptops are- especially with Google's coming "cloud-computing". Jerry Gropp Architect AIA PS Another good reason to be a “late adopter”- as I am.

I have been following this market a good bit myself, and was really stunned that you got a 36% improvement in battery life on the Toshiba. That's a lot, considering that the HDD usually consumes only 5-10% of total system power in a laptop. That number is highly dependent on software, though, which seems to imply that your test involved something that was working the HDD very hard. Any clues? A really good analysis of where the power goes in a laptop is on the University of Illinois at Urbana-Champaign website: http://www.crhc.uiuc.edu/~mahesri/classes/project_report_cs497yyz.pdf Jim Handy, Objective Analysis (Semiconductor Market Research) Nice comparison of SSD vs HDD.
