Notes about cell phones. I will be very grateful for any corrections.

Do you like cell phones? Or maybe you hate them?

I work as a network engineer and I work from home. I have to use my smartphone everyday for work. But I use it also as an alarm, photo/camera, gps navigator. I use various applications: Skype, Office, browser, banking apps, English learning apps and many others.

What would I do without my phone? It is interesting to imagine my life without using this multifunctional device.
I would have to go to the office for working. I would have to be on time for meetings because I will not have a chance to make a call to a partner whithout a cell phone. I would have to plan my daily duties in advance and with more details.

I think that smartphones make our life more effective. They help to have more (not sure irrational is the word you are looking for here)irrational lifestyle. I suppose that they are very useful devices for working and learning but with keeping in mind that they can not replace real communication.
