A smart phone is really essential on the road. It is a too steep of price to take out your portable computer, switch it on, and wait for at least one minute to check your emails. All modern phones let you check your email on the fly. But, when it comes to replying or forwarding, typing with the classic alphanumeric keyboard is a real pain. This is where the
smartphones kick in: you have a qwerty keyboard to type with, which is incomparable to the alphanumeric keyboard. For your smart phone selection, you can either go for a BlackBerry or iPhone; this is a personal choice. I have used both, and I can safely say that the two work just fine. Personally, I recommend the iPhone for the users who slightly prefer entertainment over business and BlackBerry the other way.
A smart phone, if you made an informed purchase, will save you from carrying additional gadgets such as an MP3 player, an average digital camera, a voice recorder, a travel guide, and a GPS navigator. Consider that the total sum of all these equipment will total to at least $500. The added benefit is that, with the right software, a smartphone will keep you up with local events, thanks to the increasing number of location-based services.
