I've been playing around in the last few days with the new iOS 5 and mostly with iCloud features.. I was a bit skeptic about iCloud, but I must say it's heaven for my usage! I have an iPhone 3GS and an iPad 1 wifi only... Photos: take a picture with the iPhone, wait a few secs, and there it is on your iPad, ready to be used. No more needs for apps to transfer my photos from my iPhone to my iPad. No more emailing to myself... Documents: create documents on the iPad at home (Pages/Numbers). Leave home. Open Pages/Numbers on my iPhone and the files are there, ready to be updated or simple read... No more emailing to myself, no more forgetting to send before leaving home... Update on the iPhone and iPad will be updated also... Books: read a book on your iPad. Make a bookmark on page 156 to find that page for the next reading session. Leave home, travel, wait for your train... Open iBooks on your iPhone, and there you have it, the bookmark is there. No need to remember where I was when I was reading that book on my iPad... There are a lot of cloud services like Box.net or DropBox but with iCloud, it's so well integrated that you just forget about it. It just works! I don't need apps to share data anymore and I don't have to worry about forgetting to update the other device... Yep! It's heaven for mobile computing stuff... VicoPad addict!
