Yes, IF I bought a laptop w/ 4 GB RAM I’d upgrade it to 8 or 12 GB.
Noted on the “new” style touchpads. (I’ve just had the ol’ HP a long time, it has 8 GB RAM and a 256 GB SSD, i3 processor — it does, er, did, everything I needed, quickly.)
I use (mostly Logitech) wireless mice with dongles for most everything. Granted mine are battery powered, but the batteries last quite a while, and at Black Friday prices (Rural King has their own brand @ 14 AA or AAA alkalines for $1.99 @ present, and Menards has AC-Delco AA and AAA alkalines @ 30 for $4.98 after rebate [might be a little better battery]]) cost is nil. The Logitech mice seem to get flaky slowly as the battery runs down so @ the first sign of trouble I pop in a new batt. I have yet to be “away” and have a mouse “die” from a low battery. OTOH, I have had a couple M170’s just suddenly quit. One death was a static zap, IIRC. :-(
At my old consulting gig I’d connect my HP laptop to a 27” 16:9 monitor & use both the laptop screen & the 27”, which was plenty for what I was doing (which did not involve spreadsheet work. At “home” I have a 4:3 24” Dell monitor in front of me and a 16:9 24” monitor ABOVE that (limited space to the side) w/ the latter rotated long dimension vertical. Again, not doing much w/ spreadsheets, vertical height helps me more than width.
Shortly, however, the top monitor is getting replaced with a 43” UHD TV (2021 Black Friday deal). I did a trial run and text & graphics definition is “good enough”. (Even with new glasses my “senior” vision can’t handle super tiny text such as is on some product labels.) The area should easily handle side by side (comparative) windows (data curves) and such, and, I can lean back and watch TV or a movie in the evening while paying bills (or whatever) on the Dell. (A 43” UHD screen ~1.5 meters away isn’t bad...) Then to upgrade the speakers, for which I’ll build custom units. ;-)
I play fairly high graphics 3D games on my laptop with only 3.6 gigs of ram and a Core Processor Integrated Graphics Controller.
