Summary: fantastic PC from Lenovo, I switch from Dell to this brand and totally happy with the performance for the last two years now. However, the Microsoft 8.1 upgrade had a few hiccups but here is the most crucial lesson: create a recovery flash stick to plug into your pc in case you get the blue screen of death or not able to find OS software warning. Save my goodness a few time. Looking forward to MS 10 os.
Summary: For the most part it works well, but the DVD drive stopped working after 6 months. ********************* UPDATE: This was actually caused by an iTunes update. The drive still works after uninstalling iTunes.
Summary: I bought this after an 8MG Dell just couldn't keep up with my having Adobe Illustrator, Photoshop, and internet open at the same time. I produce graphics and it is very important to me to keep multiple windows open at the same time. On the 8MG Dell, Photoshop (which I use via the Creative Cloud interface) would freeze due to lack of memory.
Summary: This machine included 'Fake Raid Zero', something that was used many years ago to speed up machines. It does not appear in any of the listed information. I was told by a tech. that if I had attempted a back up, it would not be useable to restore my computer. The only solution was to return it (and get another one, not knowing again what I would be getting) or wipe it clean and do a re-install. I did the later and installed Windows 7.
Summary: I enjoyed this PC very much. I decided to upgrade because my previous PC, which was three years old and made by HP, only had 4 GB of memory and only 2.75 GB were usable. Nowadays, the PC can be the center of all activities if one wants to. The lack of memory made the performance unbearably slow and prone to errors. So I specifically chose this model with the 12 GB of fast memory. So far I have not been disappointed. The performance indeed took a quantum leap.
