hEgelia> "Will it [USB speed] matter much to users, certainly considering RISC OS' typical filesizes, excluding media files ofcourse?
But that exclusion, media files, are *precisely* the sort of things USB speed *is* required for. Especially in a machine *whose only form of expansion* is USB - such as in the case of the A9.
hEgelia> "the Iyonix cannot fully handle theoretical USB2 speeds".
But is that more than the A9Home can manage? Yes much more. So why pay almost as much for less then ?
hEgelia>"well, from what I heard from a A9home user, it runs many applications faster than an Iyonix does"
Yes and all computer owners have machines faster than everyone elses . No, seriously that one will only be addressed when independtly verifiable benchmarks are available. When they are, and when A9 is finalised (not in beta) then we'll be able to judge.
IMHO A9 has no *technical* advantage over Iyonix. It has some *aesthetic* ones in that it is small and therefore might be the proper fit (if you pardon the pun) for certain applications, that might well be a good enough reason to choose the A9 over Iyonix. To feel the need to "justify" the A9 in some technical sense as being superior to the Iyonix is IMHO to completly miss the point.
If, however, you feel the need here you go:
Iyonix can have 1024MB of RAM (A9 can *only* use 128MB and is non-expandible)
Iyonix's 80321 Processor (a more advanced XScale) is clocked 50% faster than the A9's ARM920 derivative.
Iyonix can have 4 IDE devices - A9 can have 1
Iyonix can do something approaching USB 2 speeds A9 can't
Iyonix can accept up to 2 extra expansion cards (e.g., TV card or extra monitor card or other PCI cards driver software permitting)
Iyonix can burn CD's and DVD's (A9 currently can't - and when it does it will be slower (USB 1 not USB 2)).
Iyonix has Gigabit ethernet (10/100/1000Mb) while A9 only has (10/100)
To gain all those advantages only costs you 119 ukp.
So my advice is argue A9's *actual* advantages - its small size/appearence, rather than just either slagging off Iyonix or just pretending it doesn't exist.
