So to be absolutely crystal clear:
1] I can buy Start10, Fences and ShadowFX for 16€ and use them on five computers. I get incremental updates. Every 3 years or so I may have to upgrade them individually at a reduced price when a new version when released, otherwise my older version instantly becomes abandonware and will not get incremental updates or bugfixes.
2] I can buy Object Desktop for 23€ (summer sale) and use the apps on five computers. Every year I must resubscribe for about 20€. As long as I'm subscribed I get incremental and version updates. As soon as I lapse, the versions I have will still work (if I saved them), but are totally frozen so I do not get incremental updates or bugfixes, since the Object Desktop license keys are very tightly tied to the subscription.
Thanks for this final clarification.
