Do you use all the products or only some? How much do you use Adobe products vs the update over the previous version?
For that $15.99 a month it may be worth it to try but do the math x 12 months. $192 a year and the cost for the following years. See youtube videos and online comparisons and see if it is worth it. Have you tried a trial version of the cloud software?

I own CorelDraw X3. I could update to their latest and it would cost quite a bit but as an amateur I do not use it enough to justify the cost plus the update is not really all that different then what I got.
I use Adobe’s Dreamweaver CS6 quite a bit for home use and will not upgrade. The cloud one does have some things that would be helpful but the cost is too much.
CorelDraw is one important reason why I run Windows as a virtual machine on a Mac. I’d rather use Corel than AI any day, and I rarely do anything that can only be done on AI. However, Corel’s made that conscious decision to stay solely on a Windows platform.
With the last few Adobe Dreamweaver upgrades, most of what I've seen that's new has been server-side adaptability and Adobe's proprietary(?) code snippet goodies (I'd be more specific, but I just upgraded the OS to Longhorn, and DW is telling me I have to install the legacy Java SE 6 runtime to open it). That hasn't done much for my personal use.
Although it's much more CSS-friendly now, which is nice.
