In order for the NC to be a good tablet or whatever it is beyond a great eReader, the Browser needs a lot of attention.
I do web site development and database design. I have 7 Browsers I test against. FWIW Only Interent Explorer passes all my tests. Google Chrome is much faster, but fails in many basic page elements. Safari fails in a few, Firefox is closest to passing all my tests. Opera does fairly well. My Palm browser (a few years old) misses a lot, but considering its age is ok. My Samsung Cell Phone browser does OK too.
There are many basic things I use in page design and NC Fails in all of them.
1) Frames not supported. The browser does recognize "Target=" and displays correctly, but the whole page scrolls as one
2) Fixed background not supported. This is an important design element as it allows stuff to float over a background image
5) Videos do not play: Many sites have web cams... like our county has a beach cam to check the surf. It doesn't play (not flash) on the NC
6) Animated GIFS
7) Incorrect Browser ID The browser tells servers that it is Netscape 5.0 So some things do not load correctly . e.g. Google just changed the http://m.google.com to check for browser, and since it is presumed to be Netscape, it will not show the mobile page any longer
8) Div Tags poorly supported. These allow many design elements such as a scrolling text field on a page.
A site I setup over the summer was
Note the clock (java), calendar (java), missing background music, weather forecast, no beach cam, no waving flag, etc. Note also the three frames (Table of contents, Header inage and body) all act as one. Google Chrome misses the calandar and beach cam too.
It is great to be able to browse sites wile sitting on the swing, or to look up something on google while reading a book or newspaper. The Brower is very important to the usefulness of the NC.
Finally, I see a handheld device that can do it all. Believe me, I've tried a bunch... Tandy 100-102, Apple Newton, HP95LX, etc. I remember when a portable was over 25 lbs, or Apple sold a nice green bag for the Fat Mac and called it portable. Barely fit in overhead. While the iPad is just too big to be a handheld, the NC is perfect.
Check out the page above with IE then NC and see for yourself. I have many page elements which I'd be glad to share with whomever to help bulletproof the browser.
Of course, there are many other issues like copy & paste text, form entries, handling of pop-up lists, etc. that are in need of attention.
