The EeePC 901 from ASUS looks very impressive based on the specs. I’ve been using the original eeePC for several months and my two main concerns have been keyboard size (which I’ve become used to) and screen size (still a bit small for quality browsing). Otherwise I’ve been impressed with the light weight, small size, and fairly error-free operation with the one exception of an early flash memory failure that required a reconfiguration and lost me 100+ Hong Kong photos. Still, for $400 this unit was an amazing bargain compared to the 1500 or so I would have spent for a full blown Ultra mobile laptop in this weight class.
The new eeePC unit probably solves the screen size issue with a 9.1 incher vs the 7 inches and I assume a slightly larger keyboard. The 3.75G access could really be a boon for those in areas where that will be supported, assuming a reasonable cost by providers.
I’m anxious to hear from folks who get this unit. The mini Dell looks good as well, but if ASUS has created a comparable machine I’d be inclined to go with them over Dell based on my experiences with each company.
