i've looked around and around .. and around .. and, so far, i haven't been able to find anyone who uses an ipad to play achaea [or any mud, for that matter]. because i myself use an ipad actively, i thought i'd post a discussion for reference, for those of you who are/have been curious about the mechanisms of using a tablet device to play the game we all love
first of all .. client apps are awful.
second of all .. playing mobile is awful.
third of all .. google chrome is my love affair.
fourth of all .. iron realms, i love you.
to play on the ipad, just download the chrome app to your device and log onto the iron realms website. click 'play now' and voila! instant connection :] it has a map available, but nothing like mudlet.
playing on the ipad, fyi, is nothing like playing on mudlet. but it's still nice, though.
nevertheless, i recommend you look into buying an external keyboard. maybe a bluetooth one? personally, i have a logitech folio keyboard, and it's my baby. sigh. the battery life is ah-mazing. i got it for my birthday in april  and i haven't had to charge it at all since then. except once. and it takes like, five to ten minutes to charge. like i said, it's amazing.
i paid almost a hundred bucks for it, but it's worth every peeennnny ..
