here's what i'm trying. who knows if it will work, but i figured someone else may benefit from the info:
obviously, i signed up for the email notification from HP. i have my email program open. any incoming mail gets checked immediately, usually by my secretary.
i am following Bryna Corcoran and Mark Budgell on twitter. they work for HP and, based on their tweets, they will have the 1st info on the release of more TPs.
i already have an account @ HP, and i am logged into it. you should make an account, if you don't already have one so check-out will be a little easier and, more importantly, faster.
now, here is the HP page that i am refreshing. it shows both the 16 and 32GB on the same page. hopefully the "out of stock" will change to "add to cart" soon.
obviously the key is being able to get back to the computer in a timely fashion, but having a strategy gives me the sense that i'm not merely leaving it up to luck.
if anyone has anything better, don't hold back. we are a small minority of the people who are looking for these. the rest wouldn't know webOS if it bit them in the *****.
