The 27S might not be "programmable" in the traditional sense, but there are many use cases where the solver is quicker, easier, more intuitive, and more memory efficient than writing an RPN program. Of course, you're probably not going to want to try to use it to build a two-way ANOVA or something, but you could! Having the 27S as your primary calculator with the 20S for backup when you really just need to write a keystroke program is a good approach.

For reference, I have two of them, and they're both the older variety with the flush display lens. These seem to be much more numerous than the later version with recessed display area.

Yeah from what i read about it so far i think it's going to be really a treat to have and to use the 27s and exactly the perfect step up from the great little 20s. by the way you happened to be the one who contributed the prime factorisation program for the 20s? if so, thanks a lot : )

20s with a flush bezel? i've never seen one!
since you have both, do you mind if i sometime write you when i have a question about either? i still haven't got around to sit down and try to write my own keystroke program and relied on finding programs online. At the moment have some exams then summer break is in about a month, right about the time the 27s arrives from the US so i have then more time to learn about the 27s and also learn about how to write simply keystroke on the 20s.
