Yes, the calling functionality is great, as well as the BT handset that I've been pining for in the early days of this thread: the Samsung Stick. Asus also has a similar handset with the MeMO pad. Baseically it's like a BT headset that you hold in your hand. It acts as a speaker and a mic for the tablet unit that sits in your bag.

Now, the samsung stick is quite thin like a pen, and may not have a digital readout, or the ability to place calls easily. The MeMO handset is larger, like a small featurephone, and has a digital display that can be used as a remote for the MeMO and possibly to make calls as well as receive them.

I think Asus' solution with the larger handset is the superior one based on what I've seen, but either seem adequate.

For those that use their phones mainly for calling when out and about, these devices eliminate the need for a phone. The Tab 8.9 should be small enough to quickly whip out and use in transit, and tuck back into your man-bag/purse, providing a full tablet experience on the go. While not as versatile as a phone, it offers a much more comfortable sized screen. Best of all, you don't have to give up the 'phone' functionality at all, with the handset accessory.

Win.

Not for everyone, as many use their phones incessantly while out, but it's great for those that use their phones mainly for calling and carry a bag.

Yes, if the Tab 8.9 had a digital pen accessory, it would be killer, but maybe next revision. For the time being you can always buy a capacitive stylus -- but be careful to hover that hand over the screen whilst writing to avoid unwanted input, and writing in huge kindergarten sized letters.
