I too have been impressed with madam's new laptop running Windows 7.
Can't be arsed to upgrade other machines though, too much faffing and expense just to gain a few nanoseconds, once our exchange is upgraded in 2020 or whenever it might be tempting........ Instead I shall wait until the PC needs replacement ~ as it surely will .... as for the boys laptops, no point as they too will need replacement sooner rather than later. The THW has a Mac anyway so the question doesn't arise (even though she is really p*ssed off that her mother now has a faster, sleeker and more efficient machine than she does)
