Since App Store first launched in 2008 I've always kept all my iPhone/iPad apps in my iTunes library and also kept a backup of them on a external HDD. But it just suddenly dawned on my today, Is there any point now with iCloud? I have a MacBook Air with 128GB SSD so storage is precious, am I right in thinking I can just delete all my Apps from iTunes now that I have the ability to download them again and also backup my phone via the cloud? I just want to make sure I'm not overlooking something, I hope I'm not. I'll be able to save 4-5GB on my SSD if thats the case. Thanks.
