Nowadays, I spend all my surfing time on an HP 14" laptop, the EliteBook 8470p, with an i5 CPU, made in 2015, and running Win10. It has TPM 1.2, while Win 11 requires TPM 2.0. I will need to see if my laptop can be upgraded from TPM 1.2 to TPM 2.0.
I can swap out the i5 CPU for an early i7 CPU to get 2x increase in speed, and at a fraction of the price of the new laptop. Even the current CPU is fast enough for what I do, which is not game playing nor video editing.
The other day, browsing at Costco, I saw a new HP 14" which sports a CPU 4x faster than my current one. Son of a gun! It is also a lot lighter than the EliteBook.
I will not do anything for a while, and will wait till Win 11 comes out.
And by the way, I have several tower PCs, and they are all older than the laptop. Most run Win 10 Pro. The fastest one is only as fast as my laptop. The last time I turned one on was to do taxes, because I want to do it on a big screen. I also used another to develop firmware for an ARM microcontroller.
