Thank you very much for that great review, Getsome!
I ordered my first exemplar (yes, I'll buy another one in late summer or fall) on Wednesday and already got it yesterday (with the gratiy chrome gold minifig key ring).

So I built it up yesterday night.
I voted for
Outstanding
since this set is simply outstanding and imo not only one of the best City sets of this year but one of the best City sets ever!
Cons:
-no tools for the four boxes in the transporter
-wind power plant should be taller
Pros:
-set to make "green" energy and to show how important this is and will be
-both cars include car doors
-transporter looks very realistic
-escort vehilce looks that lovely
-wind power plant looks awesome
Of course this wind power plant can't be compared to the Vestas one since the Vestas one was much taller, included that lovely hill with the bench and the foliage plants, the service vehicle and the lovely cottage with the sun terrace.
But we should get away from always only comparing 7747 with 4999 since these two sets are totally different: In 4999 the main focus is (since it is a promo set for the Vestas company and first of all not a set for FOLs) on the wind power plant and on the cottage - in 7747 the main focus is on the tthe transporter and on the servie vehicle (since it is a set mainly designed for kids).
The transporter and the service vehicle are perfectly designed and can imo be used in all our Lego Cities (TLG even didn't forget to include car doors in both vehicles!). The wind power plant isn't very tall - but it is even not tiny. When you put it somewhere on your layout where there aren't that big houses (e. g. next to a field and the new farm - where it would btw fit the best anyway) then it even doesn't look that small.

And what concerns the lovely cottage in 4999: Since TLG asked their fans for input for new City sets last year and since one of the most demanded sets was a family house I bet that TLG will offer some family houses to us next year or in 2011.
To put it in a nutshell: Imo TLG did a great job with this set since it combines playability (which is mainly important for JFOLs and therefore even for the success of this set) and a "green" power plant (which is supposably more interesting for AFOLs). And I'm very, very glad that TLG offers us the opportunity to get this outstanding set since I can't afford the Vestas set! Thank you very much, TLG!
More "green" sets and more outstanding City sets in general on!
