I've actually been on her side of the issue in the past--though I'm the techie in the house and normally a gadget freak, I couldn't see the point in the iPhone when it came out, and thought my husband was nuts for spending that kind of money on a lousy phone--bought before the price drop, no less. The "keyboard" drove me nuts, I didn't find the UI intuitive at all, it was bigger in size than my little ancient Motorola v60i (man, that was a workhorse of a phone!), etc. etc. etc.
About 4 months later, he ended up in the emergency room & ultimately in the hospital for a week. In my rush to get out the door, I grabbed everything--including his iPhone, knowing he had numbers in his contacts that I would need.
Over the course of that week, that device was with me constantly. The hospitals here in Geekville by the Sound have all installed wireless, so access wasn't an issue. Everything I needed that would normally require a laptop was right here in my hand; I could even handle some of the emergency stuff for work via email. While he was asleep, I could follow the forums I was on, play a few games, and reach anyone who needed updates. Learned that the keyboard actually was pretty good, the auto fill in was a huge plus, and hey, you know, the size of this thing isn't as bad as I thought it would be. And I probably drove the doctors completely nuts as I argued every detail through with them--after all, I had all the background references I needed at my fingertips (and yes, caught them in a mistake).
Once he was more functional, of course, he wanted it back. LOL Yeah, buddy, here's a nice DTB and the TV remote to entertain yourself with. You put me through all this crap, the phone is mine until you're out of this place!

When we got out, he took it back & I went back to my voice-only Motorola & tried to decide if the still $300+ pricetag to move to an iPhone was doable. Or worth it. At the time, it was a budget hit I wasn't quite ready to take.
At Christmas a month later, he bought one for me and I've never looked back.
Geekbook2 is definitely in your future, start budgeting now.
Over at our place, I'm waiting for hubby to decide he has to have a K2. I figure the trip we're taking in two weeks will do him in, just about the time he has to buy a book at the airport coming home because he's out of reading material!
