Toshiba Dynabook SS MX = Tecra M6 = Portege M500?

Just want to make sure. Anyone who is familiar wirth Toshiba, would you please kindly confirm if this is true? Thank you.

I have not seen Toshiba Dynabook SS MX except in the internet, but looking at its spec & picture, I think it is exactly the same with Tecra M6 & Portege M500. I've seen Portege M500 and Tecra M6 myself. They are exactly same. It has same specs & design. But for Portege M500, it has 3 models (M500 140 has ceramic white lid, sort of like iPod white look, M500 141 haspurple lid, and M500 1401 has silver lid)

These are the links of these three models:

But I do not why Toshiba name it Portege for Asia Market and Tecra for USA Market. To me it's very confusing. But after reserching the internet for portable computer, IMHO this model suit my needs.

This week I'm ordering Portege M500 1401.Silver color, 1GB, 80GB, XP Pro for US$ 1,750. It comes with 3 years waranty.
