I'm actually happy about the hard drive. I had been secretly hoping for that. My thinking is that if my Z had a large HD in it, it could replace my Archos MP3 player. Since I tend to carry both of those around much of the time, eliminating one would be great!
So, I'm interested now in hearing more about the HD in the C3000: what kind is it and can it be upgraded to, say, 30 or 40 GB? If anyone hears anything regarding this please post what you hear.
BTW, I think some folks may have missed the point that you don't need as much flash storage if you have a HD; you install stuff to the HD instead. I'll bet they put /home on the HD. Reducing the RAM, however, is a problem. However, as someone pointed out (in a somewhat roundabout way), this may have been a design compromise to compensate for the additional power needed by the HD.
I am disappointed about the lack of built-in WiFi; my biggest complaint about my C860 is the placement of the CF slot; it makes it very hard to type. Built-in WiFi would be a great solution to this (and very convenient) with the added benefit of leaving the CF slot open for storage, etc.
Another potential solution would be to move the CF slot (of course, they didn't do that either). The problem is actually much worse with LAN and modem cards, which tend to be much bigger than WiFi cards, and built-in WiFi wouldn't solve that problem. (Luckily, I don't need to use those cards very often.)
The better (SL6000) screen and USB host would have been nice too (unlike some, I wouldn't mind a slightly larger clamshell to accomodate a bigger screen). But, these days, I guess we've got to take what we can get from Sharp. It's truly a shame that they didn't even TRY the clamshell design in the US/UK. If they had tried and failed (as with the SL series) that would be one thing; but not even trying is just stoopid, IMHO (especially when they had the existing infrastructure, that was created for the SL series, at their disposal).
Another feature that I've been secretly hoping for is an SL-style joy button that could be used when the clamshell is in its portrait configuration. There's a lot of good SW for the SL-series (games, especially) that runs fine on the clamshells in portrait mode but cannot be used effectively because of insufficient controls. There's enough wasted space around the clamshell screen that a joy button could probably be placed there pretty easily.
