Although the majority of handheld makers seem to be targeting the budget sector of the market, Sony hasn't been shy about going after high-end buyers. Last year, the company delivered the super-slick but pricey CLIE PEG-NX70V (£449 inc. VAT), and by mid-March, it'll begin selling the step-up NZ90, a CLIE with a swivelling screen. This top-tier handheld also boasts a built-in 2-megapixel camera, a keyboard, and Bluetooth support, as well as a whopping £599 (inc. VAT) price tag. This is neither your everyday handheld, nor is it meant for the average user. And while the NZ90 is clearly loaded with features and offers top-notch performance, it's a shame that Sony didn't include built-in Wi-Fi -- especially at this price.
