As discussed in the Eee thread
here, there will be a Eee 1001 with a 10" screen - probably for $299 and perhaps available as early as November. Pay extra to upgrade to at least an 8GB flash drive, and still come out ahead price wise. There may be some unique software on the Folio, but any OpenSource Linux software would most likely run equally well on both providing the Folio has an x86 compatible CPU (as all the others in the table do). If it has an ARM CPU (say) then there will be significantly less pre-compiled Linux application software available.
