It's sometimes tricky working out when to buy your new laptop, unless of course your current one is obviously ready to be retired or has just this morning bit the bullet.
But in the case of Apple's flagship MacBook Pro notebook, that time could be now. Upgrades to the 13-inch and 15-inch machines will hit the streets this week, a year after the last major MacBook Pro release and probably a year ahead of the next significant overhaul.
This mid-life revamp is aimed mainly at the power user brigade courtesy of faster 8th-generation Intel Core ' Coffee Lake' processors, up to 32GB of accelerated DDR4 RAM on the 15-inch model and a much faster solid state drive – in effect blasting away the three main system bottlenecks.
On the outside, everything's the same as it's been since the current MacBook Pro design debuted in 2016 – what's different is under the hood, and there lies some serious grunt.
For the first time, the 13-inch MacBook Pro – which we rate as enjoying the most travel-friendly footprint – packs a quad-core Intel Core processor for double the muscle compared to its 2017 sibling.
The 15-inch MacBook Pro with its six-core processors can now be configured with 32GB of RAM and your choice of Radeon Pro 4GB graphics chips so you've got plenty of headroom when working on complex extra-large project files or switching between a slew of professional apps.
Despite those pumped-up powerplants, battery life remains pegged in the 'all-day' range of 10 hours thanks to a slightly larger battery and faster RAM chips.
Both machines gain what Apple terms True Tone display technology that automatically adjusts the screen's white balance to match ambient lighting levels plus Apple's own T2 security chip for secure boot and on-the-fly encrypted storage.
And if you like talking to your computer, there's also support for hands-free 'Hey Siri' commands to save that oh-so-bothersome process of tapping a key or clicking an icon.
Keyboard warriors will appreciate a revised 'butterfly' design which softens the clackety-clack of earlier models, although we'll have to wait and see if this also improves the keyboard reliability issues which have plagued earlier MacBook Pro machines.
Note that these bump-ups apply only to the MacBook Pros with the TouchBar strip: the more modestly-spec'd 13-inch sans TouchBar remains untouched, although a small price drop will boost its appeal to business travellers looking for a mid-range workhorse machine.
Australian pricing for the mid-2018 13-inch MacBook Pro starts at $2,699, with the 15-inch MacBook Pro from $3,499.
