Many of you might have already noticed the new hotmail interface. Microsft have redesigned the hotmail and the new design is uber cool, faster and is AJAX based.
The multipane feature looks very much like the Yahoo Mail beta.
You can also make minor changes to your pictures while you attach them to your email.
Storage limit is 2 GB but serious users can expand it to 4 Gb by paying $19.99 per year. I think Hotmail should give more space free if they want to compete with other email service providers like Yahoo Mail and Gmail.
Its not necessary that you use this new interface; if you feel uncomfortable then you still have the ability to switch to old classic design .
