Mediocre. If you haven't done a proper bandwidth test then you might not realize that your *wonderful* TiBook's Airport reception is worse than an iBook (never minds PCs etc.). I no longer have my TiBook, but my AlBook is worse that my wife's iBook. Bummer, eh? I don't recall the exact numbers, but I know that the AlBook could be ~2x slower at times and *never* better than the iBook.
