Regarding free windows xp and vista, I run OS X unless I have absolutely no other choice.
Regarding a PDA I thought long and hard about such things when my last cell phone went down the tubes. I tried the Treo 6 and 7 series but found them lame and lacking in camera quality. The Sony P990 was just too bulky for me and the Nokia E61 was nice but again to wide. I use a Nokia N80 with a 2gig miniSD card. It takes pretty good pictures, OK video and has WiFi and bluetooth. The built-in web browser blows the socks off of any other I've used including the free opera browser. It also is fully 3g supported so overseas I can use the wonders of a decent wireless network.
As for keyboards all the built in ones from crackberries on down have sucked. I got one of
these and have really enjoyed it for what its built for. You can get them for sub 100 if you look hard enough.
For a journal nothing will ever beat a moleskin for the joy of writing on its paper.
I want that singlespeed wheel, damn you and by damn you I mean fantastic find.
That is all.
