I really love Googlemail, especially in combination with Google Docs, Google Calendar and my Android phone. But there is this one thing wich bugs me: the size limitation.
A set of photos or a video of the party yesterday is ofter far bigger then 25 MB. No Googlemail for that one.
But there is an easy solution for that: With Filemail you can send email-attachments up to 2 GB. The attachment is hosted on a server, the receiver of the email gets an download-link. Not very secure, but very easy to handle.
