@Robert Gentel,
FWIW, making the interface respond to mobile apps is probably wise and useful to many users with I-Pads and tablets etc. I'm sure that's pretty labor-intensive. Must be lots of tablets and I-Pads in the gene pool and coming on board.
Using A2K on my I-phone is of dubious value due to me due to the limited real-estate displayed. At least with 4G it's not slow. Though, I feel my eyes glaze over while trying to read a reply or thread, much less composing to reply to a thread. However, that's not the whole enchilada, I realize. Not a walk in the park -- rotating the iPhone to read horizontal line of text and read the comments. For me mobile means replying to PM or read-only.
