My first PDA was a Palm Pro in 1995. Over the 5 years I owned it I did RAM and ROM upgrades. In Sept of 2000 I moved to PPC and picked up the first ARM based Color PDA the iPAQ 3650 and I am still using it . The iPAQ will be updated when a PDA manufacture ships a PPC PDA with the following.
Microsoft PocketPC SE
An Intel CPU XScale CPU running at 520MHz
128MB RAM
64MB ROM
VGA 480x640 3.5” or 4.0” Display
WiFi
Bluetooth
1 SDIO slot no CF (CF makes a PDA to large)
And a form factor close to the iPAQ 4150
The Asus 730 looks like a close fit when it start shipping
My first Phone was a car mounted NEC analog AMPS phone back in 1985. I kept that for 12 years then upgraded to a Nokia 6160 TMDA phone in 1997. After 7 years with that phone I upgraded to a Nokia 6820 three weeks ago. The 6820 is a great phone that offers Bluetooth and GPRS/EDGE. That technology lets me surf the net just about anywhere at speeds up to 200Kb with out any wires using my laptop (over Bluetooth) or PDA (over IR until I get a new PDA).
My first portable computer was that luggable Compaq with the two 5 ¼ drives and a built in TTL amber monochrome display. I have had many laptops since then. The latest is an IBM T40 with built in WiFi A/B/G and Bluetooth that links to the new phone for internet access anywhere.
