Question: Does this unit have the 32 bit or 64 bit operating system?
Document: Amazingly fast, responsive, cool. The only thing I miss is a port for projectors and the battery life is a bit too low. I wouldn't call it an ultrabook.
Even after carefully following their detailed written instructions for preparing the laptop for shipment (to Bizcom), and enclosing a brief summary of the malfunction, the service order number, and the specific logon id/password (so they can test the unit after replacing the keyboard), the technician unilaterally chose to completely wipe the harddrive......now upon receipt of the repaired unit we are restoring all the wiped files.
So it's lightweight, fast, capable, etc. Windows 8 is a shame, but that shouldn't be part of this review since you can change operating systems (painfully). I put several flavors of linux on this machine over the last year. It's a great combo. Light weight operating systems on a machine built to be fast. It works. The absolute main issue with this machine is the nearly useless touchpad. Touchpads are nowhere near new technology, so how'd we make such a crummy one these days?
I purchased a Toshiba Satellite U9450-S4140 Ultrabook to carry with me when traveling or away from my desktop system. I have a technical background and believed this model of Toshiba Satellite offered a good mixture of performance and value.The Toshiba Satellite U9450-S4140 arrived in about 3 days after placing my order. It came double-boxed and seemed to be in reasonable condition. All the seals were in tact.
Ubuntu 13.04 (Raring Ringtail) works well on this machine though dealing with UEFI was a bit tricky. I am satisfied with a fast boot time and response as a result of placing the OS and application files on SSD and others on HDD. A weak battery and poor quality speakers are drawbacks, but I overcame those with a power bank (33600mAh) and decent external speakers. With those, I enjoy multimedia and a 10 hour battery life.
Less than 1 month after purchasing the laptop, 3 of the keys popped off while using the laptop. I had not dropped or damaged the laptop in any way prior to this occurring. Since I was traveling at the time, it took an additional 2 weeks before I could contact Customer Service, so I was effectively out of the return window for Amazon. When I called Toshiba's CS, the system hung up on me twice. Finally, on my 3rd call, I reached tech support.
never will buy through amzaon again - you take no responsibilitry nor protect your customers  - the most frustrating experience everAmazaon you just wash your hands over your loyal customers - I a =m out you lost meThis seller is really bad
Update:After 1 year of heavy use, many of the keys are loosing their ability. Today, the letter o popped off the keyboard and wont stay back on. Left shift and left Control are failing.Original review.I use my laptop for nearly all my work and browsing time. I can spend hours processing video, recording, writing, reading, etc.
Toshiba needs to make some improvements into the battery life, but in terms of responsiveness we got this device to boot in 11 seconds, from completely powered off to powered on state so that is pretty impressive considering this still runs a Hybrid Hard Drive. I do like that it has 2 USB 3.0s which are fantastic for flash drives and external hard drive.
Toshiba must have a lot of salesmen with nothing to do but write reviews. This is the worst computer I have ever owned. I bought it after reading rave review after rave review. The screen is shot after 4 months use. The mouse does not work well. Screens pop up from everywhere when you try to use it. So many apps and toshiba offers trying to sell you something every time you try to use the computer. A big i phone. Windows 8 is a joke.
Answer: Pretty much any laptop you buy now will have 64 bit just because it is better
