Geez. For the first time ever, the RISC OS market has two alternative high-end machines (I don't consider the barrage of ARM 7500 things worth a mention), and people can't stop moaning about which is better and why.
If you don't like one, don't buy it.
If an A9home isn't expandable enough for you, don't buy it. Your reason should be presented as "It's not expandable enough"
If an Iyonix isn't portable enough for your needs, don't buy it. Your reason should be presented as "It's not portable enough"
Everyone clear? Good. Now stop whining at each other.
