Just looking for some quick advice here. I'm going to be buying a new Lenovo T61 laptop and I've got a question about Ram. Lenovo includes 1GB PC2-5300 DDR2 (2 DIMM) with the laptop and charges $80 to upgrade to 2GB and $520 to upgrade to 4GB. I was searching around and found this. http://www.clubit.com/product_detail.cfm?itemno=CA4354065 So I'm wondering, is Lenovo charging me $520 for something I could do myself for $28.99x2? Am I missing something here? Thanks for any help.
