I'd rather not buy any computing equipment (regardless of price) whose software only the vendor is allowed to audit or fix.
I'm old enough to remember how much work went into checking and fixing stuff so that Y2K was a whimper rather than a boom.
yeah, fixable software can be patched and problems can be avoided. it's proprietary software that only suppliers can fix that has me worried, because they're more likely to leave old stuff unmaintained, unfixed and unfixable to make you buy their newer products
