Low-budget Notebooks are a tricky topic, especially if you combine it with such a huge criteria like office. (Most “gaming” notebooks don’t have any office related stuff included and most of the “office” devices are very expensive due to other things included but most of the time don’t have a dedicated graphic unit)
My advise would be to drop the office criteria and get a office version from various different sites. There are plenty of trustworthy sites that sell office licenses or you might even take some cheap/free alternatives.
In those low-budget cateogires a few hundred euros make a huuuuge differnce, especially in the long-term.
So if you can afford it i would try to aim for the 700+ price range.
Lap 3 looks really good, but i don’t have much experience with Medion as a Manufacturer.
I am not a big beliver in those 3rd party sites that compare different Manufacturers, but i can see why many people, especially people with no background knowledge tend to use them.
Here i give you some slightly pricier examples. But as i said, you might wanna consider if one of the purposes for this device is gaming, to spend a few hundred euros more. (I just included devices that come with a Windows 10 Version)
I will point out some key points that you might have or have not considered for each device. Often times people don’t think about certain things^^
- ASUS
Pro: Very good price/performance; Has 1 Available DIMM Slot Free for possible upgrade(comes with 1x 8GB already installed); 3x USB Type A(your “usual” USB) interface (2x 3.1 and 1x 2.0)
(Possible Con): No ODD(Optical Disc Drive); “just” 512 Gb storage capacity. (but very performant NVME M.2), you might consider going for an exernal USB storage device for large amount of data
- Acer
Pro: Also very good price/performance ratio; Also 1 free DIMM slot available for possible upgrade. 3x USB Type A
Con: Also no ODD and just 512 Gb storage capacity.
- Dell DISCLAIMER: I do have alot of experience with Dell, since i am working with dell for years now (i am a field service engineer doing warranty repairs for various different manufacurers, including Dell), so maybe some of my opinions are biased
Pro: Very good performance, SD-/MicroMedia-Card Reader(in case you could make any use for that), All-In-One USB-C/Thunderbolt Port; Configurator has plenty of optional stuff that you can go with, including various different office packages. Dell has very good service options, even the basic one is really nice. But also Dell offers On-Site support within different support packages that are optional.
Con: No upgradeable Memory nor Storage Mediums(also have 8Gb DIMM and 512 Gb Storage Capacity); VERY pricey, but dell does not have “low-budget” devies, since dell is kinda a more “high-quality” manufacturer. Also no ODD
As the example links you posted were all german sites, i assume you are located in germany? So i choose all german sites, but if that’s not the case i guess you can find those devies in other countries too.
If you have any detaield questions, feel free to pm me. I am happy to help or advise people in IT regards
