It's the best way I think!
And Red - you were wondering about how Synths have changed since the 70s.
I did some research into this for you, it's not particuarly extensive and is highly speculative (seeing as there's much more information about modern products rather than older ones) but I hope it'll satisfy your curiousity.
I think most of the technology developed back then and has since been perfected (or relatively speaking). For example, voices are now generally much richer and less obviously electronic sounding.
A key development since the 70s is connectivivty. You can link it up to your computer much more easily than before and use it, for example as a midi controller and indeed link a midi controller up to your synth.
The sequencer has since been developed and now is often integrated into many synths, and the same applies to the sampler. Both are technologies that have been much improved since their creation.
I suppose, with technology getting cheaper and more efficiant there have been improvements such as having greater polyphony, more oscillators etc.
I suppose the jist of this is that, in many areas, the spec will look pretty similar to what you were used to, it's just that the numbers are more impressive looking.
From there, I guess, it's mostly interface and digitalisation.
Unlike older synths, where the dials will directly affect the analog componants, the dials will now affect the computer and that will affect the analog componants.
Some synths are even completely digital.
In terms of interface this means you get things like user assignable controls. Instead of having a dial that affects this, a dial that affects that etc etc, you just 2 or 3 dials that you can program to do what you like. On my synth you get dials x,y and z, and sliders and n and m all of which are user assigned.
That example was very specific but you can see that the technology to do that sort of thing is there.
Another key change in interface was the LED screen, which, I think was instrumental (no pun intended) in the user friendliness of the modern syntheser.
Oh yeah, and they have more FLASHING LIGHTS!!!
Much Love
