I needed a laptop for simple, low-processor requirement tasks (i.e. I didn't need a gaming laptop), but by the same token, I know how the PC buying experience goes: you want as much processing power and speed as you can get, otherwise you'll just find yourself upgrading everything down the road.Admittedly, 4GB of ram wasn't ideal, but upon comparing this laptop with HP, Lenovo, Dell and others across every possible vendor (including Ebay), I am convinced the processing speed and features are an incredible deal for the money ($365 USD = Acer Aspire 5 w/ 4GB RAM and 128GB SSD hard drive). Other people suggested buying some additional RAM, and being spoiled w/ 32GB of it on my desktop, I definitely agreed, so I ordered an additional 4GB more (A-Tech 4GB RAM for Acer Aspire 5 Slim Laptop A515-43 | DDR4 2666MHz SODIMM PC4-21300 260-Pin CL19 1.2V Non-ECC Unbuffered Memory Upgrade Module) for $40 USD.I also believe more storage is essential. The Acer Aspire 5 comes with a slot for an additional SSD drive to supplement the 128GB drive, but here's where you have to carefully consider your options. You must look at sequential read and write speeds, where faster is always better. You also have to consider that you will likely have your operating system on the main (C:) drive.If I were to use the supplemental SSD slot, I would have to go with a SATA III type storage (looks like a very small, thin book). If I want much better speed for the price, I'll want to replace the 128GB "C:" drive with the same type (PCIe Gen3 8 Gb/s, looks more like a RAM stick). I went with the 1TB Crucial P5 (1TB 3D NAND NVMe Internal SSD, up to 3400MB/s - CT1000P5SSD8) for $120 USD. It's a pain to switch it out, because you have to make an 'image' (i.e. copy) of your C drive on some other storage device, then put that image onto the new SSD drive, but in the long run, it's worth it because you're coming out of the gate with much more storage and very likely (couldn't find specs on the Aspire hard drive) a much faster hard drive.So, $525 ( = $365 + $40 + $120) and you get:CPU 3.52 GHz8GB RAM1TB hard drive with up to 3400MB/s read speed and up to 3000MB/s write speed15 inch monitorunder 4lb SLIM laptopANDWindows 10.I call that an incredible deal.Now, I've read the comments about Windows 10 S. The myth is that you get locked into a system where you can only buy and install Microsoft software unless you want to shell out... man, what was it? Oh yeah, a trillion dollars. Well, turns out that's:FALSE!In fact, all you have to do is sign into your free Microsoft account, push a button and 'boom', you're off of Windows 10S and on Windows 10. No charge, no hassle, no anything. In fact, the laptop asks if you want to do this on setup, but either way, the instructions are easy to find with a Google search. Whoever wrote these other reviews apparently aren't familiar with Google searches. I can only wish them luck on their new journey to 'the internet' and beyond. I have no idea how they were able to buy this laptop or write a review.Regardless...It's true that you don't get Windows 10 Pro and have to shell out a few bucks for it ($99 at the time I'm posting, 10 March 2021), but most people don't need it unless they want to use MS OneDrive cloud storage (monthly subscription) or remote desktop. I use Google cloud (free) for some things and never log onto my laptop from another computer (i.e. remote desktop): I just take the laptop with me when I need it. Either way, Windows 10 comes free with this machine, you just have to switch it at the MS store, and that takes less than a minute.All that said, this laptop is just awesome. I love the weight, size, backlit keys and speed. Could not be happier.
