I bought my wife the 32g wifi version earlier this year and she could not be without it now. We use it primarily in and around the house and have used it at the airport and on the wifi in the villa abroad. In reality, 99% of the time will be home use. We have 2 young kids so she can wander round the house with them whilst she does the Tesco online order
She now uses it for internet, calendar, diary, notes, music (though the speaker is pretty tinny as you would expect), family photos and there are a load of games that the kids can play with without worrying about a 5 year old deleting the hard drive (like a laptop)
We would not be without one now and still amazed at the whole package and what it does. The only downside is that the wifi reception is not as good around the house on it as the PS3 and friends ipod's which is strange.
