While on paper the large Pro is "only" 63% heavier than its 9.7 inch counterpart, on hands it feels like it's more than double the weight. I find the large Pro perfectly fine for on-desk operation, but I won't want to carry it around or bring it outside my home. In this sense, it's a laptop "replacement", since my 15-inch MacBook Pro seldom (if at all) leaves my home too due to the heft.
