For the storage, pretty sure the "actual" "average" would be a SSD+HDD. And for anyone that *wants* a 2TB SSD, a SiPo is just $100. Or another $35 for a SN570.
As for the keyboard suggestion, what. Please please please, just spend the ~$45 a K582, way better experience than the cheapo keyboards (also, forget the m+kb combos, the mouse will just be ewaste beside the g502). The mouse suggestion is great, but why is the g502 wireless still so pricey
