Walt Mossberg still likes Yahoo Mail best.
I’ve been comparing the new version of Yahoo Mail, which claims to be the leader in Web mail, with Gmail, the challenger Yahoo most fears. My verdict: The new Yahoo Mail is far superior to Gmail. Yahoo more closely matches the desktop experience most serious email users have come to expect. Gmail, by contrast, is quirky and limited. Its only advantage is its massive free storage, which exceeds what most people will ever need. …
Yahoo’s new email program would blow Gmail away if it were widely released today. That’s partly due to its features, but also to its respect for user choice.
The new version of Yahoo Mail is not yet widely available. Hotmail doesn’t even get a mention.
