I wouldn't hold out much hope for it being particularly habitable. Without the early development of life you don't have a high oxygen atmosphere for most of a planet's history. Without oxygen no ozone. Without ozone UV light breaks up water molecules high in the atmosphere and the planet loses hydrogen on the solar wind. And then you end up like Mars. In terms of planets to establish a colony on I'd actually look for ones a bit outside the traditional habitable zones. You'd need a bit more in terms of solar panels and heating but lacking hydrogen is a big handicap.
