Gmail has increased its attachment size to 20mb, as compared to Hotmail which offers 10mb, half its size.
This would definitely benefit those who have suffered long enough at sending multiple emails with attachments because the files exceed 10mb in accumulated size.
And, if you're interested to preview future features of Gmail, you can try playing around with Gmail Test Labs. You can enable it via your Account Settings in Gmail. Some interesting ones would be playing Snake, and 'allowing' Gmail to log you out for 15 minutes so you can rest your eyes. Or your browser. Good for those who simply need to check their email every 5 minutes.
If you can't find it, just google. You'll find it. =)
