What changed weight on the new T-series models ?

[mouse@cheese.storage]

Dear all,


When looking at the new models of the T-series that were released in august, (e.g.: 2668P4U) they seem to have a 200 gr less weight (compared to e.g. 2668G7U), did they start using different materials for construction ? Anyone who has an idea why ?


Thanks,

Wim

PS: I have been trying to find out from the tabook ever since I realised, but the tabook link seems dead
