I have a T68i and love it to pieces. I sync everything on it without a hitch, I send&recieve IMAP email from my .Mac account, browse the net and can connect via bluetooth flawlessly. The battery life is great, considering it has a color screen (220h standby, 8h talk), a world phone, and it's light and tiny. I have had it for a while, and am still discovering cool little features.

I completely agree zarathustra. I love my SE t68i. I have used it side by side with my Treo 300, and I will be turning the Treo back in.

On the subject of BT interference with Airport, I have yet to see any interference when using the BT USB dongle while on Airport with my PBG4, even when I try to orient the computer so as to put the BT dongle in the Airport signal path. I am sure there could be, but no matter the circumstances, I have never had such a problem, and I routinely use my PB right next to the microwave on the kitchen counter!

Bluetooth right now takes channels on the 2.4GHZ frequency without checking if they're being used, which can cripple your 802.11b network. There's a new technology (I forgot what it's called) that can be implemented with bluetooth that has it check channels, seeing if they're being used or now, cutting down on interference. Anytime you have multiple items on the same frequency, you're bound to have interference. Personally, I don't use bluetooth, and I can get a constant download speed of 270 K/S with my WLAN.

The bluetooth people are hoping for 802.11a, or another WLAN standard that uses the 5GHZ, or another frequency.

You will control the PowerBook that is keyed to the mouse.

Every BlueTooth device has an ID, and that ID (along with device characteristics) is sent before two devices connect. When you PB sees a Bluetooth mouse it will do something like this:
if ( have a bluetooth mouse connected )
{
..ignore
}
else
{
..if ( know this bluetooth mouse )
..{
....connect
..}
..else
..{
....ask user if he wants to connect to this mouse
..}
}

Theoretically, the BT mouse can also limit which device(s) it will connect to, but more likely the BT mouse will allow a connection to only one device at a time, and keep the ID of the last device it was connected to to try reconnecting the next time it is turned on.

What I see is that we won't be able to use our portables in airplanes any more, just imagine the huge ammount of radio frequencies we are generating just with an iBook with booth transmiters.

Well, currently most airlines say you should turn off WiFi/Airport/Bluetooth interfaces when you use electronic devices on the plane. With built-in networking, that means turning it off in the preferences pane; for PC-Card WiFi and USB BlueTooth that means unplugging the adapter. But, yes, if airlines start having problems with people not managing their broadcasts on their own, they will likely ask the governing authorities (US or otherwise) to prohibit broadcast-capable devices during flight, which would be a very Bad Thing for all involved (airlines like that business travelers can do work on the flight ... means they fly more!)

bluetooth mouse/keyboard

How the hell are you supposed to get your Mac to communicate with a Bluetooth keyboard/mouse if some of these optimists' dreams come true-Apple packaging Bluetooth peripherals with new desktops?
Wouldn't you NEED a wired keyboard to set everything up?

And secondly, I've only HEARD that the SE 68i sucks... reading all the mobile wireless forums as I do. To be honest just about anything would be better than the Siemens s46 I was suckered into getting. I'm holding out for a Nokia that has a color screen and BT.
