I've been computing from my purse since HP Jornada offered a sleeve that fit a Sierra Wireless Aircard. I jumped ship to Apple with the introduction of its first iPhone, and have stubbornly insisted on owning each new version of iPhone. My
birthday & wedding anniversary have (in the past) co-incided with each new iPad launch. I have iPad 1, 2 & 3 with a cellular enabled mini pre-ordered on launch day. Oddly enough, I'm hanging back on owning iPad 4. I'm disappointed with the 3's weight and battery life, but the mini should solve that for me.
I'm looking forward to contributing to your community, and hope to find some answers as well.
