dimensions of the x-series?

[creative]

hi at all,

i have a question concerning the dimensions of the x-series, especially the x20/21/22/23/24. is it right that they all have the same dimensions, especially the height. because the ibm homepage says sometimes 1in and sometimes 1,2in. or is both right for all models and should be seen as an minimum-maximum-specification? it would be nice if somebody can post his opinion and tell me if all models have in fact exactly the same size or not!

thx for every answer,

regards, philip
