Openness is a feature and unfortunately it has a price, and honestly I would not care about the speed or screen resolution.
I mean the lower the screen size, the more little pixels are anyways, so why care about the resolution ?
Screen size is a stupid debate. You want a large screen to browse the web, but not too large because you will use it as a phone ? And even if it's 7 inch or 5 inch, people will try to load bigger apps and it won't work. People want to browse the web on their phone and be comfortable and not look stupid. 1st world problem, as always.
I think all you can want for such a device is to post on forums, see some pictures, chat, quickly view and answer mail, read documents, but for the rest, stop complaining and find a place to sit down with your laptop.
