I think that people are missing the point that the iPad is not intended to be a desktop/laptop replacement. It certainly wasn't presented as such. If someone needed to do work as serious as you are outlining, I can't imagine them trying to do it on an iPad. I see it as a fun device to read ebooks watch videos surf the web do a bit of email listen to music and get a bit of work done in a pinch, but not a replacement for your main computer, and I think that's the way it was presented. Also, I think we will be seeing multitasking sometime soon for both the iPhone and the iPad.
I understand your argument and agree that the ipad isnt meant to be modern day laptop replacement.
With laptops heading into the direction of quad-core, 4GB/8GB ram, SSD, or 1TB HD... asking for basic multitasking and a little scalability isn't much of laptop replacement.
My 'laptop' does much more than just blogging, browsing, and word processing, and reading ebooks/pdfs. With macbooks and macbook pros today, people are making independent movies, and running mini music studio's!
Running basic office/productivity suites on the road to do some basic research/analysis via the web and taking notes is something 10 year systems can already do. and a netbook can do this and do this quite well.
As a device that should be between a laptop(macbook) and an iphone/ipod Touch and competes with the netbooks (as well as other tablet competition coming out 2010); asking for some basic background/multitasking and peripheral expandability really isn't much to ask for. I'm quite confident this can be remedy through iphone OS (or will be be ipad OS?) enhancements... but then again; apple may never deliver it (took them long enough to implement push notifications) and there is no promise from Apple at all.
The ipad is already positioned to be a great device to view photos from your camera, (as well as network); so why wouldn't it have a built in usb port for such connection? A seperate adapter makes it feel cheap and potential to break the dock connector if shifted wrong while holding both the camera and the ipad.
Most people here are reasonable when they ask for some basic additons. these additions doesnt put the ipad as a replacement of a laptop at all. Remember this is 2010; we're ways ahead of laptop when they only had 32MB RAM and 400mhz cpu.
These are still within reasonable means of a modern day casual device... for shopping, basic research (check prices online while at stores, comparing prices between bestbuy and amazon, etc... or looking up phrases, etc), taking some pictures, recording audio memo's, recording basic video or photo snaps... do a quick import of photos just taken with the camera (without me looking the adaptor -- and losing the adapter...) so i view these photos on the ipad screen. and a webcam so i can casually chat with video conference on my couch without using a clunky laptop.
I don't see much people to pull out their macbooks, open it up, powering it up, and using the macbook to record a audio... take a picture... or compare references at target, walmart, bestbuy, or the mall.
I'd probably wont need one for myself when i already have a 3GS (but I'm still on the fence); but to be fair, I would buy one as a gift for someone else.
It's a good product and good start... I just feel it could be so much better with just a little more added. On the hardware end, I think most of us would pay $50 more (if not on the 16GB model then on the 64GB model) to have a built in usb and memory card reader (so we don't have to carry an additional adapter) and a webcam... on the software end, Apple only needs to enhance it so it enables casual researching while traveling... (this is going to be some basic background/multitasking capabilities)...
