Why gmail (not hotmail?) #1 -basic

What's all the fuss about gmail? Some good features:

1. Conversations
   Emails are stored as conversations instead of individual messages. If you've used iphone or Andriod's messaging system, you know what I mean. It's much easier to see. (Each individual message is expandable, as well as the recipients and extra info.)
    
   
    
   
2. Forgotten Attachment Detector
   If you typed something like 'see attachment' in an email, then later forget to attach it, a message will pop up asking if you forgot.
   This has definitely helped me! =P  
   
   
   
    
   
3. Undo Send
   What? Yes, Gmail has lots of 'lab' features, and this is one of my favourite. It keeps any message you send for 5,10, 15 or 20 seconds, during which you can decide to undo. To use, go to >Settings  >Labs  >Undo Send   >Enable (Really useful for when you realise the second after you send that you addressed the person with Mr. instead of Ms. or something embarrassing like that!)
    
   
4. Inbox Preview
   A static sneak peak of your inbox when Gmail is loading. This lets you quickly see if you have unread mail, and saves you having to wait for your inbox to load. To use, go to >Settings  >Labs  >Inbox Preview   >Enable
   A great saver if you sometimes have slow internet connection!
   
   

I didn't seem to mention hotmail :P Well, hotmail doesn't have any of the above features (not to the best of my knowledge anyway! -wait, hotmail has the conversation setting too!) Another post with good organisation tips coming soon! (Didn't want to overload this one :] )
