How foolish I've been. Five months ago I wrote that tablets had come of age, and even sifted my way through the line-up cherry picking what must-have features would make for the perfect device. A month later, in the afterglow - or should that be aftermath? - of the iPad announcement, I marvelled that, while Apple's slate wouldn't necessarily satisfy every user, there was nonetheless plenty of choice on the horizon for those given a taste for tableteering. Our analyst contributors wisely told me not to count my touchscreen chickens before they'd hatched onto the market, but I wouldn't listen. I thought the iPad's arrival would rejuvenate the tablet segment, but all it seems to have done is killed off any attempt at innovation.
