(1st 64bit Windows was NT 4.0 for Alpha, then 1st 64bit XP was for Itanium, one of the shortest lived versions. x86-64 XP was later)
I have some older 32 bit CPU laptops that are faster than the newer "crippled" to 2G max 64 bit Atoms (an Intel decision, the CPU doesn't even output the higher addresses), I find it annoying that Waterfox and Viber are 64 bit only.
I do hope Koval continues to support Calibre on 32bit on Windows (some quite new 64 bit Atoms with Win10 32bit) and 32 bit on Linux (some older laptops & desktops easily able to have 4G RAM and faster than some new entry level machines).
I use Calibre on several computers, inc a netbook I take out. I don't usually take my main laptop out of the house.

The amount of RAM you have doesn’t alter the fact that 64-bit Calibre is able to convert more complex books than 32-bit Calibre. Conversion will be much faster if you have more physical RAM, but it’ll get there eventually even if it has to swap out to disk. Note that it’s complexity rather than just size that determines when 32-bit Calibre will fail to convert with an “out of memory” error; I had it happen with some fairly modestly-sized books, particularly when converting to PDF. If you have a 64-bit o/s it’s well worth using 64-bit Calibre.
