Yesterday I got an invitation to open a gmail account - google's new e-mail service. Thanks to Anders Jacobsen - check out his excellent blog.
Gmail stands out from the competitors in two ways:
1: No folders - all e-mail's are categorized by labels.
2: 1000 mb storage - no need to worry about storing e-mail's with large attachements.
When composing an email, everything looks familiar, but there are two great features in gmail that is lacking in other web-based email services. First, gmail suggest contacts while typing. So when typing 'sl' gmail automatically displays 'sleepyhead@sleepyhead' if in my contact list. The second feature is spell checking. It's really fast and instead of opening a new window where you have to replace each word, gmail highlight misspelled words and you have to click the word to display alternatives.
