Hello everybody, I'm interested in these two models, I haven't decided yet. Whatever model I choose, I will upgrade its memory. Some online retailers offer this models with 512K RAM(2x256). They offer 512K RAM (1x512 as an upgrade from 512K RAM(2x256), for $40 aprox. I get a better deal if I buy memory sticks from Crucial. I think in most of the convertible models, like the T4010, the first memory slot is not user accessible, it is under the keyboard, based on what I have read. I don't know how it is in the slate models, like the ST5020/22. I would like to know if the first memory slot of these models are user accessible, like the second memory slot. Is the first memory slot located in the same compartment as the second one? Thanks for your help.
