I love my iPad, and like you, it does not detract from my Macs either. In a couple of weeks, I will be upgrading our iPhones to iPhone 4. For both of the iOS devices, I particularly love the "instantaneous" nature of the device. It is something that we have never achieved in the computer industry. The value is significant.
My biggest single disappointment with the iOS devices is their incompatibility with flash use on the web. This surprised me. I was previously unaware of level of integration of flash in the web today. I honestly do not care how this incompatibility gets solved... either Apple supports flash... or Apple takes on the responsibility to enable/drive/fund/etc the obliteration of flash on the web. It is a problem that Apple created by undertaking a holy war against flash. As a user, I expect them to solve it. Doing so sounds hard, and expensive. In any case, this would not cause the iPad to be a replacement device for me.
I love my compliment of:
27" i7 iMac
MBA Rev C w/SSD
iPad 3G
iPhone (soon to be upgraded to iPhone 4)
I especially love the way they seamlessly interoperate.

My number one problem with iOS on the iPad is the lack of Flash. People don't realize just what Flash does until they work on an Apple product that doesn't have it. The web is absolutely loaded with Flash-based websites. Some want to say Flash is only advertisements and garbage, but it's just not true. I absolutely am disgusted with my iPad anytime I try to surf the web on it. For that reason alone, I pretty much have given up on the iPad. I will use it on a flight here or there to watch a movie.
The problem with the iPad not having Flash, is the whole point of the iPad is that it's supposed to be an entertainment device. However, there's little entertainment available on the web without Flash. The biggest error in Apple's ways is to not consider the terrible loss of its customers who are buying a $499 to $829 device that doesn't have the full power of the Internet that it describes in the commercials. I feel like most buying the iPad have no idea just how bad the Internet experience is without Flash. I let various family members play with my iPad, and most of them found the Internet experience to be disgusting. Most of them said they would never buy an iPad because it cannot even surf the web. These are family members that can easily afford a $499 entertainment device, but they're turned off because it doesn't do what Apple says it does.
What is really troubling for me is the amount of control Apple wants over everything on the iPad. These developers are having to play an incredibly disgusting game with Apple pulling or denying their app's acceptance into the app store. The problem is Apple has too much control, and what's okay today may not be tomorrow. Whatever Apple does it needs to stick with one set of rules and not keep changing the rules. Jobs brags about 200,000 apps, but the quality apps are few and far between. And the biggest problem is once I have slapped down the $500 to buy my iPad, I cannot even decide myself if I want to install Adobe's Flash on it. I don't care if I lose 90% of my battery power, if I want to install Flash it should be MY DECISION. Apple often takes stances on policies that so negatively affect its customers, and it doesn't seem to rationalize the effects felt by the customers after they have given Apple their money.
I do love the iOS on my iPhone. I too will be buying the iPhone 4 the day it's released. I can live without Flash on the iPhone because it fits in my pocket and serves primarily as a communication tool rather than an entertainment tool. So it depends on the device running iOS more than the lack of capabilities of iOS itself.
I would say the nature of the iOS really comes down to the hardware and portability of the hardware that is running the software. It's not as simple as iOS vs. OS X. It comes down to usability and function given the fact that when iOS can fit in my pocket it's great, but when it cannot fit in my pocket it fails so miserably to OS X that it basically makes iOS worthless when the device running iOS cannot fit in my pocket.
I think 4GB RAM should be standard in all Macs by now, but i would rather see a Processor improvement over a HDD improvement, as the Air is really for my Uni studies only and not as a primary machine (although if the next update is significant it will be) plus i use a 1TB Time Capsule for File Storage and backup so space really isn't an issue, but SSD standard on both models would be nice, plus, does anyone know of an option to add SSD to my 1.6GHZ MBA?
I personally don't get the need for a processor improvement. I feel the 2.13 GHz CPU is plenty capable. However, what would you expect Apple go with for the next MBA? Do you believe they will go with another C2D and Nvidia 320m or do you think it will be an Arrandale CPU with Intel's GMA as the sole graphics solution? Are you willing to give up your graphics performance to get a faster CPU?
The problem with adding an SSD to both models is the cost. It costs a ton of money for SSDs versus HDDs right now. I just feel the user must buy an SSD model. The MBA experience goes from brilliant with an SSD to poor with an HDD for the end user. I feel nobody should buy an HDD model, but I don't expect Apple to give people an SSD for free. Quite honestly, the price including an SSD in the MBA was amazing when introduced in June 2009. People are already getting the SSD for free, because before the pricing update the low-end was $1799.
I believe Apple should refocus its efforts with the MBA and raise the prices back up. That way it could allow an SSD in the low-end MBA. I want a higher quality experience, and since the iPad is available for those who want less computer functions and more portable entertainment capabilities, Apple can definitely refocus the MBA again as a luxury item. Why not make a 2.13 GHz C2D, with Nvidia 320m, 4 GB RAM, 128 GB SSD for $1799 low end. Then make a high-end MBA for $2499 with overclocked SL9x00 C2D at maybe 2.4 GHz with the same 320m, use a 192/256 GB SSD, 8 GB RAM, along with an IPS display. In addition, allow the low-end MBA buyers the BTO options to add the features desired from the high-end MBA. In addition, add some more high-end BTO options available for either MBA model. They could offer 3G/4G service from Verizon for $99.
What I see Apple doing at some point is adding an LCD trackpad that functions like iOS running within a shell in OS X. This would allow touch access of the icons on the display, but the user would touch them on the trackpad instead of putting their greasy mitts on the display. I also see Apple using a hybrid drive method soldering maybe 32GB NAND Flash to the logicboard which will run the OS and apps. Then the user can select either HDD or SSD, but their Mac would be as fast as SSD for the OS and applications where it is primarily needed. Apple could also use some of their cool patents allowing motion sensing interactivity with the OS. Or they could finally implement a liquid cooling solution to run a faster CPU in the MBA. They could even offer colors or even just black aluminum in Mac models. I see the MBA as the idea launching platform for Mac notebooks. Apple can test future possible features on the MBA's as a luxury feature allowing Apple to refine the experience before going mainstream into MBs and MBPs.
At the end of the day, I am willing to pay ridiculously for the products I buy from Apple. However, I want Apple to give me the options to buy new/current technology even at ridiculously high prices in an MBA that isn't from October 2008. I don't care how insane the prices are, we should have the opportunity to spend ridiculous amounts of money on current technology ensuring Apple gets paid handsomely for the sales of the MBAs. I also want my iPad to run the software I tell it to run not what Apple permits me to run on it. As consumers, we need to demand more from Apple. I want Apple to WANT to take my money. It is bad that Apple refuses to update several products as it's forgetting about its long-term relationships with Mac users.
