I have been reading through this with a bit of a smile on my face. I can see where he is coming from on some aspect (just not to the same extent) and disagree with him on others.
To start off, I do not like Apple Macintosh computers. I am a Windows XP user (have been since it was released), I have 5 buttons on my mouse (and a scroll wheel). I have spent the last couple of months playing with an intel mac running tiger and like the smoothness but not the (what seems like) money grabbing (£122 to upgrade to snow leopard before I can upgrade iTunes to accept my tablet and phone).
I also own an Archos 605 media player (IMHO) the second best media device I have ever owned (first being a iRiver), some creative zen stones and numerous other music and media players. I am also privileged enough to have had a first generation Windows XP tablet edition PC (such potential, so underpowered it made is terrible).
I do own two apple products though. The iPhone 3GS and the iPad 2 3G, both in black and both 16GB (I couldn't afford to get the bigger ones).
To start I think the price of the iPad is a little steep, granted the wifi version is cheaper but to me that's like chilli with no kidney beans (I know about tethering). I got mine for £200 as I was taking it out on a contract with my mobile phone provider (long term costs more but I get a 2GB + 10GB wifi hotspots per month, so getting a service). Making it a little more affordable for myself.
I have had my iPad 2 a week today, it hasn't left my side. I'm using it right now with the iPF app. Its not a computer in a way that I see it but it is an amazing little device. It bridges the gap between mobile phone and PC. My PC is always running but lacks the portability of my phone, my phone lacks the screen and capabilities of my PC. The iPad is the best of both. I can take it with me, like my mobile, and use it almost anywhere.
I strongly recommend getting GarageBand, it's worth the £2.99 just for the sampling keyboard (I tend to be very wary of buying apps). Also get AirVideo, I don't use the streaming ability as it'll eat into my allowance, I use it to convert my Divx movies so I can locally stream them to my pad via my home wifi.
I love my iPad 2, it is a toy (to me) but a very much loved one. Great purchase.
