The picture to the right shows to you what a PDA or rather Pocket PC can do for you.
It is captured from the screen of a Dell Axim X50v. It is shown in the
original resolution of 640x480, i.e VGA resolution, compared to the QVGA that is the standard for most PDA(personal digital assistant).
You won't be able to get the exact layout above because it's screen display is modified. It took lots of efforts reading information in websites, especially http://www.aximsite.com/ and http://www.xda-developers.com/
before I can show the above display. This is despite the capability of the Axim X50v Pocket PC machine that runs at 624Mhz using Xscale, an uprated ARM processor, with a VGA display. Even them, I encounter lots
of bugs and display problems.
For a complete discussion of the things that you can do with Pocket PCs refer to the Mobimate ebook "What I can do with my Axim 2nd Ed." at:
(http://ebooks.aximsite.com/ebooks/Tutorials/).
One reason why I embarked on PDAs with VGA display my dissatisfaction with browsing using small displays on the Palm devices, that were called PDAs earlier. I never bought any Palm.
Instead I use a Sharp ZQ-1400A organiser, that is as big as a
calculator, and consumes electricity at the rate of 0.01W, which
allows three coin lithium batteries to last for 6 months. The greatest problem I had with this organiser is the lack of connectivity with PCs.
Colleagues use the heavy, clumsy and expensive folio diaries, which I never use. Earlier I carry pocket calculators.
Pocket devices are useful for me but are not that effective. I still miss my appointments and had to rely on other people to remind me but calculators are the most useful item that I carry where there is no substitute.
However these devices must be pocket sized and easy for me to enter alpha numeric data. Advances in technology allows us to do even more with our pocket devices. Pocket Personal Computers, such as this Dell Axim X50v shows the way but there is little support from manufacturers and Microsoft. They overprice these devices despite their smallness and ease of programming. Pocket PC devices tend to use downgraded versions of desktop devices so should be simpler and smaller.
Dell has stopped manufacturing and supporting Pocket PC devices. Only HP is left. None of the Eastern companies manufacture purely Pocket PC devices. They manufacture Smart Phones that use small QVGA screens and consume lots of electricity, making batery life shorter.
Competitions are coming. The US$100 OLPC ( http://laptop.org/) and US $400 Kindle shows the way. Kindle (http://www.amazon.com/Kindle-
Amazons-Wireless-Reading-Device/dp/B000FI73MA) is only an e-book reader with 800x600 resolution but it has sold out.
All these are based on the Pocket PC technologies. Their problems is that they don't fit into a pocket, but it allows bigger screens. They should be able to replace the much heavier laptops or notebooks. In fact, despite their names of laptops, they are never used on the lap. Too heavy and fragile. OLPC is the first truly laptop PC. They should never replace the pocket devices.
Will mobile phones replace Pocket PCs? The common view nowadays is that it should. It is backed up by the number of devices sold. Buyers forget that these devices consume so much electricity, that it will make its battery life shorter. I already see a few colleagues buying simpler mobile phones to back up their smart phones that are only equipped with QVGA screens.
I carry two mobile phones, and one Pocket PC. One mobile phone is the V3x, a 3G capable phone, equipped with QVGA screen (240 x 320 pixels, 33 x 45 mm). This is the smallest screen that a QVGA can support because it will make the text sizes too small. Apple's Iphone should be the biggest multi-purpose phone (screen of 320 x 480 pixels, 3.5 inches).
Apple's Iphone is an interesting new class of device. It combines the popular Ipod with a mobile phone. It cannot be used effectively as an ebook reader. The strength of Iphone and Ipod has never been in the hardware. Whatever it tried to do, it was already possible to do with Pocket PC devices, and even more. I can play divX movies clearly(tcpmp), and now can even edit pictures and convert them into different formats(xnview). Now with Softmaker's Textmaker and Planmaker, we can edit documents that we produce at desktops. Unfortunately it is not free.
Most of my Pocket PC software which I quote here can be used for free. What is missing is the OpenOffice class of software for Pocket PC. If google managed to develop the Android, the linux for Pocket PCs and smart phones, my ideal Pocket Personal Computer will materialise.
An excellent article that talks about the same topics:
