OK, lets look at this rationally. Here are your issues with ipad and my response why they don't make sense.
iTunes required for uploading content--Not sure what the issues is here since this is a great application to maintain all content.
No Flash support in the web browser--Flash is dead. HTML5 is the future and most sites support both
Poor still cameras Ė though, really, this thing isnít meant for taking candids--Really, other than facetime, why would you use the ipad to take pics/videos
No standard USB port--What would this bring? To access files? Ever hear of dropbox or box.net?
No kickstand Ė it cannot stand on a table without the help of a dock stand or a Smart cover--Buy a case
Non replaceable battery--I have had my ipod for 3 years now and use everyday. Battery is still working fine. Non-issue
No stereo loudspeakers--Buy a dock with speakers. It is not meant for hi-fi output
No GPS receiver for the Wi-Fi only version--
No memory card slot--Again, use dropbox or box.net to transfer files.
3G model uses micro-SIM, instead of a regular size SIM--And?
iPhone apps designed for HVGA resolution squander screen real estate or look pretty bad uspcaled--iphone apps are not meant for ipad.
