Just because you can create cute things like a little song or a slideshow with music doesn't make the iPad a true creation tool. Moreover, it doesnt make me a hater that I disagree with you. How the hell can I be a hater when I use my iPad daily for hours? The OP sounds arrogant is definitely generalizing many people just because he found a few cool things he can do with his iPad.
I'm an engineering student and a tech reviewer on YouTube. As far as school goes, the iPad is nearly worthless for note taking. My classes are all math, physics, and chemistry based and there's simply no way to replicate 90% of what I see in class efficiently on my iPad. Don't even get me into graphs. I can make much more detailed notes on paper in less time than I can on the iPad. For anyone looking to do SERIOUS professional grade video editing, the iPad won't cut it either. It's not powerful enough to edit lengthy 1080p videos, not to mention it doesn't accept a majority of file types out there and you need to buy a separate camera kit to import videos. The iOS version of iMovie is a novelty right now. It's good for people who want to throw something cute together, but for the serious editors it's not good enough.
Let's just all throw away our laptops and computers, we don't need them anymore with the iPad!
How do you know the quality of what I created? I don't remember posting the files here or giving out links. I also don't remember saying that I was a serious editor. I said that for the way I personally use a computer, the iPad is doing the job just fine. My family members, knowing that I'm the nerd that I am, often ask me to put together videos, slide shows, etc. for family events. Usually I do this in Windows Movie Maker, which is more robust than iMovie for iPad, but is also way more complicated than my video editing abilities. I am not very artistic when it comes to that kind of stuff. Most of the time all I need is slides plus music, and I would venture to say that unless you do that kind of thing for a living, or even semi professionally, you don't need anything but an iPad.
As for GarageBand, this is an opposite situation than iMovie for me, because I have a degree in music and DO have the creativity to handle more robust software. But despite its limitations (the main one being that it only supports 4/4 time), it is still a terrific creation tool. I don't play guitar, but I know how to put chord progressions or riffs together because I know music. GarageBand is a terrific CREATION tool for laying down an idea or creating an accompaniment to something else you're doing. And the built in mic is surprisingly good at picking up vocals, which shocked the hell out of me.
I'm not saying there is no need for computers anymore. I need one for work. I need one at home. It's still very hard to distribute or share any of the content I'm creating without burning to a disc or converting it to some other format. I also still need my computer as a media server for our home and to create and store backups of all my important media files.
What I am saying is that people are hanging on to full blown PCs for dear life because A) it's a change of paradigm that they're not willing to go with and B) for some of us (I'm work in the IT profession as well, guys) in the future it could end up meaning some changes to our professional lives in various ways. What you are overlooking is that while engineers, professional editors, etc. still need a full blown powerhouse PC to get things done, those types of users do NOT represent the vast majority.
Apple is in tune with this, and that is why the iPad is selling like hotcakes. Where they've impressed me is that they've made me interested in devices like the iPad when I'm actually more of a PC power user. I have a quad core Windows 7 machine at home that I built myself and designed for gaming and to handle more labor intensive software that I use. I have an extremely powerful computer at work that even dwarfs the one I have at home. But when all is said and done, I now prefer using my iPad to either of these two machines and have since sold my underpowered and inefficient 17" laptop.
To each his/her own, but I was just telling MY story, not telling you how you should live your life.
