I have purchased the personal version of SP and found installation and registration very easy. My disappointment has been in the limitations of the personal version that were not apparent in the SP comparison charts. I have not found a way to use any of the resource cost data. It may be of value to enter the data for a team where there is one Pro version to analyse the costs, however the personal versions can only use the data for a reference. The Gantt chart is only editable in Pro, and that feature and cost reporting may make the move from personal to Pro SP a must. The help manual is too succinct to the point of appearing to be a features list only.
