The word "compromise" comes up a couple of times, but the problem is people don't seem to want to compromise on anything. A phone is a device for making & receiving calls, a PC for internet/emails etc, a camera for taking photos and so on. If you add up the physical size of all these items you have a pretty large amount of kit - even if you have gone for the slimmest laptop and smallest camera. Then people expect what's probably the smallest of these gadgets to be able to handle all the functions of the other items just as well as the original.
Well I've got news for you guys - current technology means you just can't do that!
When I first went to Symbian I was amazed at the functionality available in a device as small as the Series 5; now people expect the same functionality in a mobile phone plus a load more.
But I'm the same as a few of the posters above, I want my phone to make/receive calls and texts. I think I've used the camera function about 3 times in the last 5 years. If I want to browse the internet I find the screen is too small, the functionality limited and the keypad too fiddly - the device is just too physically small for comfort. So my compromise is to wait a short while until I can get back home, or to the car where the laptop is.
