gollark: It isn't just formatting. For stupid historical reasons, there are two units, GiB (gibibytes, 2^30 bytes) and GB (gigabytes, 10^9 bytes) which software and people will happily mix up all the time.
gollark: Also poor controls relative to using computers with keyboards and such.
gollark: Also having to pay by subscription for access to games.
gollark: Latency, mostly.
