John Ellenby may not have been the father of the modern clamshell laptop, but as the CEO of Grid Systems, the first company who successfully commercialized the clamshell laptop in 1982, Ellenby was an early influencer of a trend that would set the standard for how all laptop computers look and function today.

What are the chances of a device running iOS or Android to be infected by malware? While 5-6 years ago those odds were slim and insignificant to the average user, now mobile devices are just as much at risk to be the target of hacking, as any Windows laptop, or Apple MacBook.

The iMac Retina 5K, the most powerful Mac available aside from the aging Mac Pro, isn’t likely to get a redesign this year, as that would work against Apple’s traditional tick-tock cycle of releasing brand new products every other year, which makes the MacBook Pro a much more likely candidate for a reboot which has been rumored for some time.

If you own a MacBook not older than 4 years, depending on the configuration, you might still have a chance to sell it for quite a bit of cash, or get a considerable rebate towards a brand new model, with one caveat, which is a narrowing window of opportunity to act. Once that window closes, it will cause the value of your old MacBook to precipitate considerably.
