4 June 2007 – The Psion Experience

This isn’t my first time using a Psion device, but it is my first time using the Series 5mx unit.

First impressions of the Psion 5mx are favourable.  It has a nice keyboard, a decent software suite, a large screen and a quoted long battery life.

In use, the 5mx isn’t perfect.  The keyboard, whilst large, is still cramped compared to my foldable keyboard I use with my PalmOS devices; check out my article on PDA input.  The screen is large but can be difficult to use under certain lighting.  Fortunately many of the applications available for the device have a global zoom facility, which improves visibility.  Psion claim a forty hour battery life but this is using a profile of ten percent active use, ninety percent idle time.  I tend to use the device when it’s switched on and it doesn’t idle for long before being turned off, I see between fifteen and twenty hours to a pair of alkaline AAs.  This isn’t bad but it just goes to show, don’t believe the hype.

The Psion 5mx runs Epoc32, which is an early version of SymbianOS.  Epoc32 is fast, stable and efficient.  It is bullet proof using the standard applications.

If the Psion does have a weakness it’s in the connection to another machine department.  PsiWin, Psion’s connectivity software, is unstable and prone to simply not working.  Synchronising ones personal information database between Microsoft Outlook and the Psion takes quite some time and occasionally refuses to work properly.  It doesn’t help that the 5mx uses a serial connection, which compared to a USB device, is slow.  One can also convert Microsoft Word and Excel documents to and from the Psion (and they are transferred very well too) but I don’t see a way to synchronise the files between the two machines.

This highlights how the Psion is supposed to be used.  Whereas a Windows Mobile device is very much chained to the desktop, the Epoc32 device is a standalone computer.  The Palm personal digital assistant sits between the two - it can be very much a companion to a desktop but for me personally, I use it more as a standalone machine.

It is a flawed device but it is also very powerful too.  It’s a good writing tool... but is it as good as a PalmOS device with a foldable keyboard?

I’m still undecided.  On the one hand I am writing this review on my Tungsten T3 and portable keyboard but this is because of the difficulties I have in connecting the Psion to my notebook computer so as to post onto the website.  On the other hand the Tungsten T3’s battery life is three to four hours and the combination of T3 and keyboard is larger than Psion 5mx.

If PsiWin offered a more robust connection, the Psion would make a more tempting prospect.  At this time, it is relegated to one of my writing tools and I continue to organise my life using the Tungsten T3.

3 April 2007 – Another Change

I’ve been reconsidering my choice of primary personal digital assistant.

I’ve been running with my Tungsten T3 for six months now.  Since then, I’ve replaced my PalmOS GPS navigation software with a Garmin unit, which is even more portable than the Tungsten T3.  I’ve replaced my MP3 playback functionality with a Sony Walkman mobile ‘phone.  I also replaced my mobile email solution with a BlackBerry for a short while.  So what’s the Tungsten T3 been doing?

It’s been doing what PalmOS devices do best: personal information management and a writing tool when used with my foldable keyboard.  It’s been doing plenty of things but nothing that taxes the gorgeous 320 by 480 pixel screen, 400 MHz processor and 64 Mb of memory.

I could get by with my spare device, the Palm Vx.  Even if I find the Palm Vx’s screen difficult to work with that is.

A trip to Africa has highlighted my concerns with the T3.  Yes, it’s a wonderful machine in many respects but on an airliner, its four hour (at most) battery life barely scratches the surface.  An hour and a half on a train then two hours waiting at the hotel sees the device almost out of power and the aircraft wheels are still very much on the ground.  At least the Vx will give up the ghost when one is about to be served a meal...

Would I be better served with a more “back to basics” device, something that sacrificed the quick processor, ample storage space and beautiful screen for battery life?  Yes I could be, except, I’d miss many aspects of the T3.

How about a Psion?  The Series 5, especially the 5mx, has a very good reputation.  Yes, the Psion 5mx is larger than the Tungsten T3 but it has a built-in keyboard.  I need to bring my T3’s foldable keyboard with me if I’m to do some serious writing and it’s slightly too wide for an airliner tray.

Psion 5mx users make do with a monochrome 640 by 200 pixel screen, by T3 has a 16-bit colour, 480 by 320 pixel display.  That’s twenty percent more pixels in a smaller area.

Epoc32, the Psion 5mx’s operating system, manages to combine PalmOS’ simplicity of with Windows Mobile’s complexity of operation, throws in some nifty features (such as stability) and just works.  The 5mx is a pre-Bluetooth, pre-802·11 wireless device so you don’t have access to wireless technology beyond infrared.  You do get a CompactFlash Type 1 slot and replaceable AA batteries.

That’s right, the device is powered by AA batteries.  Uptime is reckoned to be in the region of twelve hours with the backlight in use or twice this without; Psion quote a forty hour uptime, but this is with the keyboard in use over four hours and the device turned on with the screen in use for the remaining thirty six hours.

Experience tells me that twenty four hours is around two weeks of my ordinary use.

But do I want to give up my Tungsten T3 for a Psion 5mx?  I’ll find out soon enough, I’ve bought one, now I need to settle down with it.

12 November 2005: My Ideal Device(s)?

I am drawing closer to one of my ideal personal digital assistant solutions.  But first I should take a step back and reintroduce what one of my ideal devices would be.

Okay, combination devices are a great idea.  If nothing else it allows one to integrate the contact database with a means of calling, emailing or sending either a MMS or SMS message.

The Tungsten W‘s weakness is that one could not place the device to the ear and needed a wired headset.  The Treo 650 does not have this weakness since it has onboard Bluetooth and will happily communicate with a Bluetooth-enabled headset.

Getting a PalmOS device to communicate with a cell ‘phone is nothing new.  My old Palm IIIxe supported an infrared connection with a likewise equipped cell ‘phone.  My m515 with the Bluetooth card would happily communicate with my Bluetooth-enabled Nokia 6310i.  And my Tungsten T2 will happily communicate with my Sony Ericsson T610.

I can use the Tungsten T2 to send or receive messages (currently only SMS, I have not investigated using MMS via the Tungsten).  I can make data calls using the T610’s GPRS or a conventional data call.  And I can use the Tungsten T2’s address book to dial numbers, placing the call on the T610 for me.

I’ve bought a Bluetooth headset, a Sony Ericsson HBH-662.  This is a Bluetooth 1·2 compatible wireless headset with caller identification.

The caller identification facility is fully compatible with the T610 and if a number in the cell ‘phone’s memory calls me the headset displays the name.  Very neat.  Otherwise it shows the number.

Readers may query the logic behind having the headset show the caller number when one would be wearing it.  Yes, however at the office I try to avoid wearing the headset unless on a call... with the HBH-662 my ‘phone can live in my briefcase and I can make or receive calls using my personal digital assistant and the headset.  The Tungsten doesn’t leave my side and the headset fits nicely over the numeric keypad of my computer keyboard.

As well as the caller identification facility the screen also shows a battery and status: this is good news.  Now I can see when it needs a charge.  More importantly the HBH-662 does not have a blue LED on it.

This is surprisingly important to me and the reason why is because all blue LEDs I’ve seen on either a PDA, Bluetooth headset or ‘phone are bright.  Very bright.  Dazzling bright if you’re in darkness, such as when driving at night.

In conclusion, although I have three Bluetooth-enabled devices (cell ‘phone, PDA and headset) for most of the time I can use just two.  The cell ‘phone can live in my pocket or my briefcase and only needs to come out for either charge or for MMS.

It’s not quite as elegant as a combination ‘phone and PDA but it will for the time being.
