I would imagine that the process of concentrating the tea extract into solid form involves a lot of heating, which would boil away chemical compounds of lighter weight.
I can't say how those compounds affect the aroma and taste, but again, they will likely be missing from this solidified form.
One of the claims that are being made about this type of product is the process they use to extract the beneficial properties of the tea. Theoretically, you could get more of the beneficial properties out of a product like this. Personally, I don't drink tea to solely benefit from the properties. I like the process of brewing, taste, aroma, and fiddling with the tea ware. With a product like this, all the above are missing and you are left with a product that is more like taking a supplement. The taste and aroma are much more subdued and almost unrecognizable from the original leaves. I would have no interest in buying and using this kind of product but I can see how it could be marketed as a 'tonic' which the Chinese, in particular, seem to have a fondness for.
