Quest for the Ultimate PADD

I’ve been a fan of portable electronic organizers since my first one in the 1980s. I’d like to share my thoughts on the evolution of these devices through a historically review of the ones I’ve owned while on my quest for the ultimate PADD.

When I first started watching Star Trek:The Next Generation in 1987 I was fascinated with the small handheld devices that the crew were using: PADDs (Personal Access Display Device). These allowed access to all the knowledge of the Federation and appeared to have virtual infinite abilities. I wanted one.

Along came 1989 and I made my first purchase of a device that kicked of my dream of owning my own PADD.

Sharp IQ-7000 (1989-1997)

Tech Specs: Screen: Mono 96×64, Memory: 16KB RAM

The Sharp IQ-7000 was essentially a glorified pocket calculator. What differentiated it from the pack was that it had a built in calendar for planning out your time and a contacts button to store al your phone numbers and addresses. It could take short notes and had all the normal calculator functions. The unique selling point what that it had a port to take custom application cards that converted a section of the device into a touch pad. These cards were bought as add ons and included cards that could manage your accounts, add a dictionary to your device or even boost the meagre memory up to 64KB (the first SD card?) This device kept my vision of the ultimate PADD open for a number of years until in 1997 when along came a device that was closer to my dream.

Psion Series 5 (1997 – 2001)

Tech Specs: O/S: Symbian EPOC, Screen: Mono 640×240, Memory: 4MB RAM + 6MB ROM, CPU: 32 bit ARM 7100 (18.432 Mhz)

This big selling point for me was that this device had a touch screen. I was one step closer to that PADD dream. This was a proper little computer that had most of the functionality of modern day devices. It accepted Compact Flash cards and hence you could build up the memory (I recall buying a 32 MB CF card for £80 ($120) and thought this was an amazing amount of memory). This device had a word processor, a spreadsheet app and even stored photos and took recordings. It’s database app was one I used a lot, filling it up with databases of Star Trek episodes and details of all my favorite films. I loaded it up with all my contacts, diary, personal data and databases and had access to them wherever I was. At the time this was all cutting edge stuff, and then along came a new kid on the block.

Casio Cassiopeia E-115 (2001 – 2003)

Tech Specs: O/S: Pocket PC 2000, Screen: Color 240×320, Memory: 32MB RAM +16 MB ROM, CPU: 64 bit NEC VR4122 (150 Mhz)

Now this was a proper little computer. It was even running a simple version of Windows. This device felt like my ultimate PADD. It was the right shape, it had a full color screen and no keyboard. Compared to the Psion it was ultra fast with a 150 Mhz processor and had no problems storing all the info I ever needed and was compatible with all my PC applications so a cinch to update and link to all my documents. It did play music and video, but that 32MB of RAM didn’t go very far (anyway the 5 GB iPod I got in 2001 sorted that need out). You now had the ability to install custom applications like simple games and apps that could simulate the night sky (cool!). The device was still a bit  bulky for carrying in your pocket and had terrible battery life (that big 3.8” TFT screen was cutting edge but power hungry). It took regular AA batteries and ate them like candy – very expensive. I needed something more fuel efficient.

HP iPaq 2250 (2003 – 2005)

Tech Specs: O/S: Windows Mobile 2003, Screen: Color 240×320, Memory: 64MB RAM + 32 MB ROM, CPU: 32bit Intel XScale PXA255 (400 Mhz)

This was the evolutionary step up on the Cassiopeia. The basic design was very similar with a screen only slightly smaller at 3.5” but this device had been on a diet with the weight dropping from 255 g to 164 g. It also had a rechargeable battery to save my pennies and a much faster processor. The cost of memory was rapidly coming down in price and was now up to 512 MB SD cards for £80. I could now store some video files (mainly clips from Star Wars) and store lots and lots of databases. I liked this device a lot. It hit a lot of my PADD buttons and I carried it everywhere in my pocket where it competed for space with my phone (these had yet to shrink to the ultra tiny devices of today).

HP iPaq 2750 (2005 – 2007)

Tech Specs: O/S: Windows Mobile 2003 SE, Screen: Color 240×320, Memory: 128 MB + 128 MB ROM, CPU: 32bit Intel XScale PXA270 (625 Mhz)

In 2004-5 wi-fi was the big thing and home networks were springing up everywhere. My next device was a faster, slicker version of the previous iPaq. The big selling point was that it had wi-fi built in. It quickly connected to my wi-fi network and suddenly the whole of the internet was at my mobile fingertips. My mobile (cell) phone had already been doing this for a while over the WAP network (very slow, but it was still the internet). The iPaq gave a bigger cleaner internet experience with the big screen and ability to pick up email. Memory was now ultra cheap and I loaded it up with 4GB of flash memory and started to load full movies onto it (Star Wars being my first film). It even streamed video over the net and I remember getting live Shuttle footage from NASA TV showing the earth slowly rotating below. While surfing the net I found a piece of Windows CE software that created a Star Trek inspired interface. My gadget finally looked like a Star Trek PADD! I was now very close to my ultimate PADD.

Nokia N95 (2007 – 2008)

Tech Specs: O/S: Symbian OS 9.2 Series 60, Screen: Color 240×320, Memory: 8GB, CPU: 32bit Texas Instruments OMAP 2420 (332 Mhz)

Through 2006-7 the life of the Pocket PC was being overtaken by the increasing power of phone operating systems and software. My old Psion Series 5 operating system, Symbian had gone on steroids and had turned into Series 60. The Nokia N95 had a step down in processing power and flexibility from the iPaq, but gave me a camera, video, GPS, cool N-GAGE games and oh yeah, a phone! I also had the whole internet at my fingertips virtually anywhere (not just with a wi-fi signal). This was truly a gadget that I could carry anywhere, have access to the worlds knowledge and never get lost with. Was this my ultimate PADD?, No, I needed a touch screen.

iPod Touch / iPhone (2008 – )

Tech Specs: O/S: iPhone OS 2.2, Screen: Color 480×320, Memory: 32 GB, CPU: Samsung ARM (533 Mhz)

Now I have to admit, my iPhone is still in the shop. But with my iPod Touch and N95 I have full internet access on the move (courtesy of Joikuspot software). To me my iPod Touch is as close to my Ultimate PADD until they actually make one. It is portable, has a great touch screen and now with the Application store has been opened up to thousands of applications. Of course I had to search for a PADD application and my prayers were answered with ‘Tricorder’. I may not be able to shutdown a warp core with it, but I know feel like I’m on the Enterprise. Clearly the iPhone is closer to my goal and as soon as my contract runs out, a fresh one will more than likely be in my pocket.

Looking back at my Sharp IQ-7000 it’s hard to believe how much the portable orgainser has evolved. It was only 10 years from the Psion 5 to the iPhone and the technology advances were significant. What will the next ten years hold? Somehow I think my Star Trek PADD is still a few more years away.
