so my nook color went belly up on me.. my geek squad warranty got me a full replacement or exchange for an upgrade. so i took upgrade.. but i did little to no research as i had expected them to just fix it.. so asking the sales rep when isaw the tablets i asked " whats the diff from the 8gb to 16gb" his reply "storage space" .. now i come home head to xda only to find out theres a ram difference.. question is.. is there a huge difference in the ram usage? do any android apps really need more then 512 ram? or should i just fork over the extra 50 bucks and get the 16gb
