Wifi's still pretty bad, but it was really bad then. Especially on consumer wifi routers, but most business set-ups sucked then, too. Dropped packets galore, signal-loss hiccups, and not enough bandwidth to make up for that by transferring large buffers really fast. Terrible for streaming. Probably way more battery-draining then than now, as well, since that kind of hardware has generally gotten a lot more efficient. Wouldn't be surprised if that efficiency has outpaced increasingly demanding standards.

[EDIT] I don't mean to be dismissive of a feature you'd have liked, I just think that, given the context of the time, I can totally understand why they'd not include that.
