Re: Sigh
my real user review of the Lenovo P50 is it works ok(about $3600 loaded up including 3 aftermarket Samsung SSDs and 4 year on site support). 98% of the time in Linux(with a windows 7 VM for some work things), 2% of the time in Windows 7(bare metal).
I think if you don't want the crapware you most likely have to pick a small OEM that installs vanilla software. For me it was more important to have on site support so I wanted a big name vendor. Previous laptop was toshiba (bought in 2010), worked fine though support was a year expired and I didn't want to risk my primary work machine being without support anymore.
Vulnerabilities like MITM to me are such a low threat level for most users it's just a knee jerk reaction by people a lot of times. Most technical folks will practice relative safe computing habits(I don't recall being infected with a virus or malware since roughly 1992), and hopefully not using (m)any public wifi access points to reduce attack vectors.
Less technical folks are likely to be compromised 100 different ways before anyone does a MITM attack against them.
I remember my grandfather before he died was apparently addicted to granny porn. He bought a Dell computer, would go to the porn sites, get infected, then after a few weeks or whatever the computer became mostly unusable, he would call up Dell, they would remotely reinstall the system, and he would go at it again(this was about 8 years ago maybe).
Windows 7 OEM end of sale date is coming up pretty quick (end of Oct 2016), and even now it can be difficult to find systems that will ship with it. MS has worked with big players like Intel to ensure lack of compatibility going forward with older Windows systems on new hardware, my company's PC supplier told me some horror stories about their customers rushing to stock pile compatible equipment before the hardware is no longer available(sometimes literally selling out while they had them on the phone).
