i have not try this out yet but it certainly sounds like an unified inbox. or close. security issues aside, this is a great idea. we can check multiple email accounts (of different providers) via our email client, but online? Windows Live Hotmail has the answer. you can now check your SingNet, Yahoo! Mail, GMAIL and of course, your Hotmail in one log in. saving you the hassle of logging into separate accounts. i am sure we will asking about security issues, especially when it is Microsoft. how safe is it? will it make life easier for hacker? now that the hacker can access to all your email accounts by just getting into one. hmmm. no? in anyway, i suppose this will be a common practice eventually when cloud-computing becomes a norm. there’s also competition from portable devices such as smartphone and iPad, which already offers unified inbox.
more info @ Windows Live.
