The Price of Portable Technology

I picked a 11 devices I've used or have held personally and researched their release price and date. Using this inflation calculator, I came up with this table:

Release	Company	Device	Initial Price	Inflation Adjusted Price
1988	Sharp	Wizard OZ-7000	$299.00	$512.00
1993	Apple	Newton Messagepad	$800.00	$1,109.00
1996	US Robotics	Pilot 1000	$299.00	$383.00
1996	US Robotics	Pilot 5000	$369.00	$472.00
1997	Psion	Series 5	$599.00	$744.00
1998	Toshiba	Libretto 70CT	$999.00	$1,220.00
2002	Sharp	Zaurus SL-5500	$499.00	$556.00
2004	OQO	Model 01	$1,999.00	$2,135.00
2005	Nokia	770 Internet Tablet	$359.00	$371.00
2006	Samsung	Q1	$1,099.00	$1,099.00
2007	Nokia	N800 Internet Tablet	$399.00	$399.00

With that, I made this graph:
Click-pop for larger. I don't claim that all my research was correct as it was simply the result of Google searches on the devices, but it is interesting to see that the Nokia N800, with it's 800x480 color wide touchscreen, WiFi, and Bluetooth cost less (adjusted for inflation) than a 512k Pilot 5000 with a 160x160 black and green touchscreen. The 5000 didn't even have a backlight!
