I can say that the biggest reason for not wanting a iPad is because of the lack of decent multitasking, also I need and want a qwerty keyboard, myself I got a Nokia N97 just because it has both qwerty and touchscreen. (I know symbian aint great with no direct acess to the framebuffer etc when coding for it but I bought mine before I knew about the N900, might add I have a port of UAE on my N97)
Also a quite big reason is the lack of JVM on the iPad! I need JVM!
Also I have not liked apple since they went from PPC to wintel

I can admit I have a apple in my posession, but its an old iMac G3 with a 266MHz cpu that I bought a G4 expansion for and buffed it to max ram and me and a few friends hacked together a custom firmware so I could put Mac OSX on it. but that mac was only for the fun of doing something impossible with (before you write that the iMac G3 can run OSX let me remind you its the first REV and it had no supported FW to do so)
Enough talk about my old projects... I get carried away sometimes when writing so sorry

But as said, no JVM and qwerty are my strongest points also I do not like the OS, its to simple for me and feels somewhat they are aiming for young girls (no offence).
Also as im a linux nut I have preordered a Pandora
http://www.openpandora.organd thats a omap3.x handheld with full qwert and touchscreen and gaming controlls, as JamVM is in the repos all we need to do is build a plugin for Firefox on it and we are done! Ops allmost forgot to tell its a linux based machine

Dont take this as advertising, I just love this machine and been with it since the early planning stages

So no iPad for me ever!
Sorry for the long post but im typing from my N97 at work and I get carried away :p
