Both notebooks feature the new Santa Rosa Centrino platform and will ship with the Intel Core 2 Duo T7100, T7300, T7500, and T7700 processors. They use the Intel GM/PM965 chipset and come with Windows Vista 32-bit/64-bit or Windows XP Pro.
They also use the new Wireless WiFi Link 4965AGN from Intel, the Robson cache memory technology and the GMA X3100 IGP chip will be available for laptops without discrete graphics card.
Both the Lenovo ThinkPad T61 and R61 feature a 14.1" WXGA or WXGA+ LCD display. Both models will be available in May.
WWAN models of the T61 will first become available in June while The R61 will be available with a Blu-ray DVD burner beginning in July.
Also of note with the new notebooks is that Lenovo has finally removed the "IBM" branding from the palm rests. The IBM branding has been a leftover vestigial since Lenovo purchased the company’s PC division in 2005 for more than $1 billion USD.
