“512GB SSD; & When 256GB or 512GB Available Lenovo website shows in Features Tab up to 512GB SSD available, altho Specs Tab says only up to 256GB. I confirmed on 11-Sep-2015 with Lenovo Tech Support that their master parts list indeed shows 512GB is (or will be) available. Will Best Buy offer this configuration? If so, when will it be available? How about the 256GB version, which is now (11-Sep) on your website? (Lenovo Tech says taking a 256GB SSD and then upgrading it later to 512GB might not work, and likely would be very expensive; so getting a 512GB config initially would be the way to go, if that's the capacity one really desires.) And a general suggestion: If Best Buy is advertising a new item that's not yet available, an accurate estimate of availability would be v. helpful.”
