I grabbed a Verbatim 1Gb flash drive for $24.99 at Office Max, last week, when they went on sale. No Rebates.
Already have several Sandisk 256Mb from earlier this year (4 for $44 at Costco).
Then, being that I rebuild hard drives, took 3 of my 'free' 80Gb drives and put them into Firewire/USB2 cases at about $31, each.
Very transportable data!
Also, on my network, all data is free to flow between the drives, under my control, as LVM (Logical Volume Management) is integral to Linux. With Linux tools, can move files worldwide.
Microsoft uses Linux on 45,000 MSN, Hotmail, and Microsoft.com systems, following the huge ( $$$ profit!) success of Google.com.
In their commercial zeal to follow the money, they never even knew the power. http://pclinuxos.com
