I have a friend, architect, does project execution as well.
He bought an iPad, $1000, to replace his $400 laptop, says it is compact, rugged, all solid state.
He also got a padded bag with a sling to carry it around.

He shows the contractors on site what is to be done, says picture is worth a thousand words.

I think it is a good idea for moving around, though you can also use a cell phone with a big memory to stream music / files.

A little off topic, but see how many people have 10 year old laptops in daily use compared to people using 10 year old desk top computers.
Laptops seem to have a shorter life..

Off topic:

Business use laptops have normally a longer life than consumer models. For starters consumer models normally have battery than is fit for 300 recharge cycles where business models have 1000 recharge cycles. And if you charge at 20% and stop at 80% then they last even longer - it's settable in the BIOS.

I'm getting longer life out of the Windows business laptop than out of the couple of Mac Mini's I'd: they lasted only 4 years. Alas I'll have now to go for a different brand laptop next as I do not trust the Chinese manufactured ones any longer. Who knows what backdoor they are building in.... I've stopped the automatic BIOS upgrades...

Modern hardware cannot have a complete security; the complexity of the different devices requiring firmware to operate make security an almost impossibility. Since firmware is often closed source no one can be sure to know exactly how secure their machines are.

Intel CPUs, are for instance, capable of running an entire hidden operating system on a hidden dedicated core. The hidden OS is Minix.

Needless to state, when I learnt of the above, I stopped being too paranoid about security, although I still take it seriously by updating my OS and by refusing to save personal financial information on my computers.

The solder sucker I just bought has he silicone tube tip, and replacements. I've never had one of those before. But in this case the 1mm wick did the trick.

I did manage to bridge the ribbon crack with fine strands of wire. Took some effort, I'm not used to working at this scale, and it's been years since I did SMD work. Not pretty, but fingers crossed it will work. The tracks repaired are; ground, V+, ground. The thin unbroken tracks on the left are LED return lines.

Tomorrow will be more flux cleanup, cotton strand removal and reinforcing the ribbon from behind with some thin plastic taken from the solder sucker package. I don't want it to bend and crack again. 😀

Really neat work. Wile you're there, it might be a good idea to lay some wire along those other traces. If you can. It'll help stop the crack from spreading. Finally, perhaps, use a small piece of flexible sticky tape (Duck tape?) on the back of the ribbon to reinforce it.
