Nokia has just announced its 770 tablet Internet device, intended for use wherever a wireless connection can be found. It's not a PC in any real sense, just a device for surfing the Internet, listenting to Internet radio and, promised, with RSS feed.
I can see this being the next "must have" toy - to be without one in Business Class airport lounges (not places I frequent much myself!) will be the same as being undressed - very embarrassing. It's quite tiny, however - 141 x 79 x 19 mm, which I translate as 5.5 x 3.125 x 0.75 ins. (approximately :-) ). (I wonder what it is about the old 3 x 5 catalogue card format that keeps it popular - does it follow the Golden Mean? Mmm. I've just checked - it does, the two numbers are side by side in the Fibonacci series. That must be the answer.)
