I'm on my 14th hour of using the ipad 3. I left ATL this monring at 8:30 and am currently on a flight going back to ATL from Laguardia (6 hour delay... frigging LGA). I've watched almost two movies, used twitter, facebook, instagram and maps..... read several tech blogs... and even downloaded some albums using iTunes match. I'm currently at 26% battery remaining. I left my house without a charger for either my phone or ipad... and this is all I carried. Long story short is...... This is something my MBA can not provide for me (I have the 13 and wife has the 11). I mean.... I love the MBA.... but using an Ipad with the combination of the Logitech UltraThin Keyboard has helped me be productinve in so many different ways today. I kept Cellular Data on all day (except when on plane when I switched to GOGOAIR... which is how I'm typing this post). Longer story short...... Why can't the same battery go inside of the MBA?? Am I missing something? I forgot to add, I emailed a LOT as well as frequently surfed while in LGA.
