If you're like me and you work from home, you know how important it is to have a computer that can handle your workdays. I've went through various different brands of laptops because they've either been slow or have had bad battery lifespans. I picked up a second job at a hotel working the front desk and these are the same Lenovo M900 computers we use. They run 24/7, 365 and are abused with dust and running hot with absolutely no breaks in between. They are the fastest and have no issues whatsoever even under the excessive loads. I bought this one for my work from home job and I already know it's going to be with me for the remainder of life. This was my first and only choice as it is slim and easy to take anywhere. Mind you I've spent way more on laptops than I did on this, and this little monster out performs them. If you want something that can be packed in a carry-on and can go with you wherever, this is the one. When you do order this, the seller includes an external wifi adapter that plugs into the USB port, and yes, to answer your question this is wifi compatible.
