I'd be willing to bet the Novatech Airware with IRIS Orb outsells it. Its a good price for an OK system, perfect for non-Hackers who still need a little computing power. That or the Meta Link, the commlink of the masses. Its ideal for people who mostly just need the equivalent of a phone and web browser.
Oh, KI was just joking, because the TA is the link which is perfectly suited to be upgraded to full 6/6 hacker stats.
Every hacker who does his homework gets a Transys Avalon. It's like the "Rating 6 Medkit" of hacker gear. No reason to go for anything else save for the flavor of it.
