To try free of charge for one year a software that costs 20 dollars annually is a nice opportunity.
The usual and customary trial time is somewhere between 15 days to a month; that is not enough time to test whether the programs one wrote using a competitive suite actually work or can be easily modified.
Furthermore, in this case, other versions of this suite supposedly are compatible with, for example, Linux; if one wanted to leave Windows behind, the migration would be easier.
The centered advertisement is a bother; it would be nice if the vendor shows it every 20 times, or once every week, when the suite is started. That facilitates testing and does not take away the vendor’s right to state that he is the copyright holder. The good part is having twelve months to check out compatibility; once one is satisfied, one should purchase the annual license. That is my personal opinion.
Thank you for this opportunity.
