I am impressed by this laptop.  I was expecting less performance given its specs, but its actually quite good.It is running a 3Ghz Tiger Lake Core I3 and 4 GB 1600 MHz of RAM.  The RAM is really where I think this laptop could be better.  If this had 8GB or RAM, I would have given it 5 stars.  I thought that maybe I could use ReadyBoost to supplement the RAM, but ReadyBoost apparently is not supported when the PC has an SSD.  I decided to define my own Pagefile of 12 GB  and to not allow it to resize itself.  Sure, I loose some storage in doing so, but this laptop needs some RAM.  Since the 4GB is soldered on and the user cannot upgrade it, the Pagefile was the only way to go.  Besides the lack of RAM, everything else is great.I bought the separately-sold Lenovo Active Pen 2 for this and the writing experience is good.  If you write slowly, you won't notice any lag between where you pen touches the screen and where the line is  drawn.  If you write faster you will see some slight lag (or gap onscreen between where the pen is and what you just wrote).  Overall, it is good enough for writing.The keyboard is solid.  I use a Thinkpad at work, and have used Thinkpads for years.  This laptop keyboard feels like 90% as good as the Thinkpad keyboard.  If you close your eyes, you might even think you were on a Thinkpad.  There is no red eraser style Thinkpad pointer nub on this laptop.The trackpad is a nice size and I don't feel like I need the massive size of a Macbook trackpad.  It is the "diving board" style, where it clicks physically at the bottom half of the trackpad, but not at the top.  Of course, tap touching works all over.What surprised me the most was its single-core Geekbench 5 score.  It scored a 1284 for the single-core and 2450 for the multi-core score.  I ran Geekbench 5 a total of three times after the laptop had been on for a few minutes.  Those were the best scores I recorded for this laptop.  So this Core I3 is no slouch, but it is only a dual-core.  For comparison, my Dell XPS 13 (model 9310), running a 4-core Tiger Lake Core I7 scored a 1546 single core and 5628 multicore.The color is a very nice dark grey. The top feels like metal and the bottom feels like plastic.You cannot upgrade the ram, but you are supposed to be able to swap out the m.2 NVME ssd.  The bottom cover can be unscrewed for this.  I have not done so.After being fully updated to the latest Windows Updates, I have 64GB of 117 GB free.Mine came with a barrel-style charger, but I have been charging over USB-C with no issues.Overall, I am quite happy with it.  I wish it had more RAM, but if you try not to multitask too much, Windows seems to be ok with it.
