May I humbly suggest:

I have not used it myself, however, though I am thinking seriously of  
getting one.  I'd be very interested to know if it runs Squeak well,  
as one of my main concerns is how well I would be able to use it for  
development.  Probably it can't handle Eclipse, but I figure lighter- 
weight tools like emacs or squeak would probably work quite well,  
apart from the small screen size.
