Oohhh! I have one (had it before the iPad) and I still take it with me to dentist / hospital/ hairdressers appoint,menus because it's small enough to tuck into my bag.
If you don't have a kindle, you can download the Kindle app and read books, but it's not the best thing to do on it.
I have: (not the definitive list!) Crosswords Scrabble Thesaurus Dictionary (Chambers is best for both) Met office BBC news Tune in radio Facebook Google maps (amazing) Whirly Word Amazon Saga Woteva TV Guide Peppa chick etc. etc. Complete Works of Shakespeare Nearly all my music Angry Birds I have a small docking / charging station (£25.00) so can play the music easily. And all these apps, once bought, can be downloaded on to iPad.
My Android based smartphone does all that and more.... being a "connected" Granddad and Dad..... it links to google calendar..... no excuses for anyone in the family not to know what I am or not doing....+ 1 for the Kindle app too..... as well as using Ndrive as a sat nav with traffic too.... radio and music player... and full high speed 7.2mb mobile internet...happy days...
