I have a 2+ year old Lenovo ThinkPad R50e with Celeron M, 0.75 MG memory and running Windows XP- Pro. The local "computer guru to go" talked me into purchasing a new- more powerful model: TP T61, 7500, 4 MG memory, Centrino Pro and came with Vista Business. As someone who struggles with basic Windows and Word applications- trying to learn Vista at home- while using XP at the office is just NOT A GOOD IDEA. Lenovo told me because I hace Vista Business- I am eligible to purchase "XP downgrade" from them for $ 60- $ 75. I never was able to understand the answer to why I could not just transfer the XP-Pro on my R50e to the T61- in order to execute the downgrade. Seems like they are just trying to see how much $$ they can squeeze. I'd be more than happy to spend that extra $$ with the tech who I am going to have to hire to do the actual downgrade- even if I do purchase their "Downgrade Package". Is it possible and also practicable to try to transfer from one laptop to the other I appreciate the assistance ! THANKS !
