Of course, with fix-focal lenses, they can only get it wrong for someone, no matter which focal lens they choose.
If you really want 21+30, then 24+50 is wrong. No question about that. (There is also a 30/3.5 Macro now available – if you can live with its slow aperture and probably even appreciate its 1:1 macro feature. Personally I'd have liked this to be a 30/2, and even as a macro lens it really should at least be a 30/2.8.)
Time will tell if there will be a sufficient lens choice for the NEX so that everyone could get what he or she wants, as with Leica M, for example, where everything up to about 90...135 mm is covered by several manufacturers in the smallest possible focal length increments.
By that time, hopefully also the new "G" standard zoom has emerged. BTW there are some image examples at dpreview.com taken with the already available 18-55 kit zoom. I personally don't care too much about the performance, and I strongly dislike the built of this lens: Metal on the outside, okay, but *inside* where it matters most, its really wobbly plastic.... but still that kit is surely not bad in general terms and far from useless on the 24 MP sensor.
If you want to call all this "pocketable" .... well it won't fit in my clothes pockets, that is for sure, but then, I consider nothing else than a slim mobile phone really as pocketable in this strict sense. (Other people might have clothes with bigger pockets.
However, the NEX would still offer considerable downsizing when compared to a typical DSLR outfit, in at least the same sense that a Leica M outfit does. I need a seperate camera bag anyway, no matter which camera system, but with the NEX, this bag will be lighter and smaller as with my DSLR, and I appreciate that very much. Last not least, the NEX-7 seems to offer really nice handling. So, again, they have just found the *exactly right size* at least for my preferences, and everyone's elses mileage may vary, as always....
