Extremely valid point...
Only things is - Apple thought about this...
SD SLOT: I knew Apple would not include an SD slot on such a small storage device. This is a common 'play' from Apple as they are moving away from "making" products for the user (best features in their best products). These days, Apple Inc. like most other firms in this down economy are geared towards sales, and Apple ultimately wants you to spend more than the introductory iPad at $500. The 16GB iPad model is purely for market saturation & "marketing" a price point in general.
CAMERA: I think not including a Camera is the biggest flaw in the iPad. I have very high hopes for the iPad in due time. When the iBooks market has been well saturated & 4G(LTE) rolls out in the next year or so - Everyone will have or want one!
FLASH: That is just a pissing match! Jobs & Adobe both have sides that I could take, but I think on the whole, Flash is not the future. I mean Jobs is correct, when he talks about Flash crashing web browsers. But in the present, it is widely used & Jobs should know that and have already implemented this into their OS for the iPhone, iPad, & iPod Touch.
No matter what, they missed out on marketing this as a portable device that is great for video chat. I still think the underlying reason is that this is a marketing/sales ploy to have you purchase all three platforms - iPhone, iPad, and a Mac.
I'm still getting the iPad over any Netbook out there. If I need a netbook when traveling I will bring my MacBook. But, for the most part, all I need now is...
The iPad!
