Indeed, this is something I've wondered myself, since in my experience even 100g does make a big difference in a tablet. But I've come to the conclusion - it's hard to really pinpoint the "cost of repairability". Taking the numbers: IPad Pro 12,9: 692g Surface Book 2 13: 719g Surface Pro 2017: 770g Elite X2 1012 G2: 800g Surface Book 2 15: 817g Of course, the IPad pro shines, and apple certainly are famous for "shaving off every possible gram" - but it's just so different a platform, esp. thermals, that it's hard to make conclusions towards "cost of repairability". The Surface Book 2 tablet modules are light for their size, but I'd say this is primarily bought due to a significantly smaller battery compared to the SP and the Elite (23Wh vs 46/47Wh) - batteries are heavy. The only devices here realistically comparable IMO would be the Surface Pro and the Elite X2. But IMO the more interesting device I've posted for this kind of comparison (even though I wouldn't consider +/-100g that critical here as I would with tablets) is the Fujitsu U937, because it's one of the lightest x86 notebooks overall on the market, while still offering competitive specs in all metrics (CPU, RAM, ports, battery size, display size, etc.) and still being easy to repair/upgrade. (Too bad that keyboard and touchpad are rather mediocre :( )
