Wall Street is thrilled that it at last has something to cheer about with regard to IBM, and the two days since the Silverlake launch have seen the shares put on $5.875 to $123 even: while the AS/400 should stem the attrition in the System 36 base and keep most 38 user happy and contented, IBM’s bigger problems remain, but the very positive reaction is well-founded, because IBM might have come out with a product that looked like a dog almost from Day One – it has done so before – whereas there is little wrong with Silverlake, and importantly, the third parties who have to sell it are very happy.
