Last November I bought a MBPr 15". Nothing too fancy. 256 SSD. 8GB RAM. I have always been a Mac person. But ever since I bought this machine, a lot of my business colleagues told me "its not a business machine", "you wont get any meaningful work done on that", "who needs a chunk of aluminum anyway", "you wont see half the colours on that retina with your naked eye". I already had installed Parallels on it (for Excel on Windows). Last month I decided to actually see what else is on the market. Lenovo being the market leader for Business laptops I thought I would order a few and see which ones compare to my MBPr. Worse case scenario, I would sell my MBPr and keep one of the Lenovo machines. I got the ThinkPad T530, and the Thinkpad W530. The T530 is a bulky machine. Though not heavy. It does most things right. But and this is a big but, the screen is horrendous. It has a constant blue hue on it. Also the ratio to aspect is crap. Everything is tiny. Viewing websites is a big headache. All the fonts are barely readable. You have to magnify or zoom in for each and every article you read. The W530 is supposed to be a desktop replacement. It costs me $3K. Loaded machine. I also maxed out the specs on the display with a colour sensor and with NVIDIA graphics card. Got 16GB RAM. A 16GB MSATA drive and 500GB hard drive. (I got an extra charger and a laptop bag). As you can imagine, I was pretty excited when this machine arrived. I quickly turned it on and WTF? The screen still had a blueish hue to it. I had to re calibrate it every week. Big no no. Since the maxed out the specs on the screen, the resolution was super high. I could hardly see my icons on the desktop. The web? Nightmare. Super tiny fonts. I tried three browsers just to make sure: Chrome, IE and Opera. All the same. I had to have zoom on 125% all the time which made Youtube unusable. Even the speed of the booting up and shutting down was pretty slow - what did the MSATA drive do anyway? I returned the two machines back to Lenovo and I am so thankful I have my MPBr. Sure I might need to carry a few dongles in the event I go to a conference. Big deal. My MBPr screen is the best. I stare at this thing a good seven hours of the day - it better be good. Sorry Lenovo. You might attract the "we need a real laptop which can dock" crowd but guaranteed they you lost a customer in me.
