6. AT&T/Samsung Galaxy Note via Best Buy ($300 with two-year contract)
You can't sell unless you get your client's attention, and out in the wild, with all its mobile distractions, attention is the scarcest resource. While you should not confuse the Samsung Galaxy Note for a smartphone -- this thing is far too big for that -- it makes a surprisingly effective presentation tool.
Whip this baby out and people will notice.
I found that Samsung's roughly 5-inch diagonal screen is crisp, bright and easy to read and its AT&T (T) 4G LTE connectivity is blazingly fast. You will find not only the 8 MP outward-facing camera solid, but the 2 MP front-facing camera excellent as well. Plus the unit comes with a stylus and software that allows you to mark images and take written notes. The Note takes a bit of gadget jujitsu to make all the parts work, but if you connect it to a mobile projector (see item 5) and do your homework, you will have a heck of mobile presentation system.Even better, the Note has been a cosmic -- and I mean cosmic -- flop. Consumers run from this thing because of its size and complexity. So deals can be had. Start at Best Buy (BBY) and drive as a good a deal as you can.
