While my post was more tongue in cheek, there's a kernel of truth. Why should we find "work arounds" to those short comings when there's a solution that's already more extensible and costs pretty close to an iPad. I mean price out a MacBook and its pretty close to the cost of the upper end models of the iPad.
I'll probably get an iPad, not as a laptop replacement because in that way, its a poor solution, but as steve put it, an in-between machine. The idea using it for e-books, light surfing (light because of no flash) and various other tasks makes sense for me. I'll not have disconnect my laptop from all of the stuff its hooked up to on my desk just to use it in my living room.
I agree it's not a replacement at all. My thoughts were limited to MBA vs iPad not taking into account the MB. I do however find the iPad a better solution for me than the MBA for the simple fact of what I use a portable device for. Lots of video, web, email. I've own'd 3 variations of the MBA, the concept is great, I find the hardware rather cheap. Hinge sucks, weak and falls apart. Heat vents on the bottom, great news when it's resting on your lap... as a leg cooker.. I mean warmer. HD video.. forget about it, you have to do some "magic" of your own to get this to work. Not to mention the trackpad is just sad after using a glass one in a MBP.
So MBA at 1500 w/HDD which is slow.. or a flash based device for 499 it is a pretty easy decision for me. Flash can always be pointed out, but apps make up for a large portion (aside form Hulu) of the video content, for me anyhow, on the iPhone OS. Youtube, CNN, ESPN, NYT, TMZ etc... and so on. Flash is not missed on a device that offers many, many free apps that portal the content specifically to the device. If this was the iPad with a modified OS X that did not use the app store, but made use of traditional programs with touch controls yet restricted flash. That would be one bag of hurt I would pass on.
