About 3 weeks ago, I got a Smartphone Qtek 8060 powered with Windows Mobile 2003. Well, it changed my life!
Before having that device, I had a Nokia mobile phone and an iPaq PDA (read about new HP iPaqs here). That was 2 devices to carry at all times. 2 devices to take care of, 2 cables connected on my desk at all times for battery reload, 2 contact lists and synchronization methods (+ a special piece of software for the Nokia), etc. I looked at the Qtek 2020 that took me closer to the PDA with telephone features but still, it was too big for me.
The 8060 is what I wanted. It's first and foremost a telephone. You have the ability to use it and carry it as if it were just a classic telephone. You reload the batteries once per day, you put it in its beltpocket when you leave in the morning and that's about it. However, it has the versatility of a PDA. (Oh yes, you also have the ability to turn off the phone features but keep the PDA features available).
As far as connection technologies, it uses GSM, GPRS and Bluetooth. Through GPRS, I got it to work with my Exchange server (for my mails, my tasks and my 500+ contacts) and with an Internet Browser ... in minutes. It automatically synchronizes with my Exchange server every hour so I'm in touch with the office and I have all my contact (speed dial is a dream!) and tasks info wherever I go. There's also a very nice feature called the "Automatic Mode" that changes the telephone mode (silent, normal, etc) based on your schedule so you don't even have to remember to put your phone on silent when you go in a meeting. Bluetooth comes in handy when it comes to using a headset or a GPS software!
It has a little camera but, really, it's more a toy than a real tool. There's multimedia support through Media Player. There's a "Voice Note" capability that really is great when you think about something while driving your car. Once again, the key thing is that you actually do have it all at all times!
I even installed maps of cities. Can you imagine having, in your telephone, the map of the city you're in, with hotels, points of interest, museums, etc?
Hey, and through the use of the Compact Framework and the convenience of Visual Studio.NET, you can also have your own applications on that device (DVD list, train collection, work hour registration, traffic counter, games, etc). I've put an extra SD card of 128Mb in ... and I never had to use it so far!
This smartphone also has some bad sides: The battery does not last long enough for one full day heavy use (say from 6.00AM to 11.00PM) so the craddle is very helpful to reload the battery when you're at the office; the navigation pad is not really the very best I've ever seen (to say the least); there is no voice dialing feature (that was available on my Nokia)!
If I have to summarize: It's an amazing productivity tool that you have with you at all times, even without thinking about it. It comes handy more often than you think. I strongly recommend it!
