imagine being in a high stakes cash game or deep in a tourney with high blinds, and you're in a pot, let's say you have half your stack in the pot, with a hand you are willing to go all in with that you feel will win the hand, i.e. Ace high flush or a boat, and your opponent bets out and as you're about to call him or go all in, your connection craps out due to crappy 3g/E signal. and the poker site automatically times you out after xx seconds. i don't know about you, but some of the cash pots i play get pretty sizeable, and the last thing i would want is to lose a hand and the pot because i timed out due to a crappy signal
sure it could happen on a pc, but less likely
