I did some looking at them last night, for less than the asking price of $309/unit you can pick up an Icom F5021 with 125 channels, and for slightly more you can pickup a Vertex 4600 series radio with 512 channels; most radio shops will program them new the first time for you for free, so you wouldn't need to worry about a software package and programming cable. Vertex and Icom have a more reputable name, and are a little more of a known entity.
Now looking at the spec sheet there, and having read through some of the manual, if you already had your Ham Radio license, I could see the VFO mode being a nice feature when traveling; and if it is indeed certified to be used off of the Ham Bands (they claim FCC certification in the manual, to which part I could not tell) then that would be a nice rare feature on Part 90 gear.
Those for buttons on the top do worry me about installation options, when the head is permanently attached to the radio. I haven't actually used one so I can't speak to menus and how well they preform for what they advertise.
If I were in your shoes shopping though, there are at least a few other options that I would seriously consider if you're looking at the radio as an investment that you expect to last you 20 or more years.
