A history of handhelds before the iPhone. For those too young to remember.
Palm V
Thin metal body and integrated battery. First must have handheld.
Handspring Visor with Springboard Cell phone. 2000
Sony Clie T665 running Palm OS 4.0 2002
I did mp3s, ebooks, Office documents, and video yes video (including episodes of Southpark) on this thing in 2002. It also had a commercial grade IR blaster for controlling AV equipment. And a high density 320x320 display and memory stick expansion.
Sony Clie NZ90 2003
Everything the the T665 had plus 2 megapixel rotating camera with flash, removable battery, ARM processor, 320x480 screen, compact flash slot for memory or wifi, on board Bluetooth, and keyboard. Also a simple web browser and could run Flash circa 2003.
Palm Lifedrive 2005
I still have this one working. Arm processor, inboard wifi, Bluetooth, 320x480 screen, SD card and 4 GB of onboard storage. It was a great multimedia handheld for movies, music, ebooks and surfing. I used to post to ATOT with it. There were about 30,000 apps available for it.
All of these were years before the iPhone.
The one thing the iPhone did have was the first really decent mobile web browser.
Posted from my 5s. Sigh.
