More lost business for the IBM Personal Computer Co has come to light in the pages of US PC Week this week: the paper hears that one of IBM’s 30 largest customers, a diversified East Coast manufacturer, has ordered more than 1,000 PS/2s in the last several months, but has received fewer than 150 – and estimates that the revenue IBM has missed on those 850 machines is about $3.5m based on their estimated street value – The waiting is so bad that we’re looking at another vendor, said a consultant for the customer; and another major customer has been waiting more than six months for 250 ThinkPad notebooks, a sale worth more than $1m.
