Question: How many USB ports does this have?
Document: Room for a second hard drive. 17&#34; 1920 x 1200 screen. HDMI out w/Harman Kardon speakers AND 4 USB 3.0 ports for $800.00. The older/current software I'm using doesn't require a dedicated video card and the older packages that do are very well served by the HD 4600.
Bluetooth is horrendously unreliable (Microsoft's fault, not Toshiba's I assume) so you're kinda forced to use a USB mouse. Modern dongles don't stick out a lot but with a 17&#34; laptop there's usually no room to spare in your bag so even that little dongle sticking out gets caught behind the zipper all the time. As long as the USB ports don't break off (you hear me Toshiba?) that should be not too much of a problem.
Hardware is as advertised. This is a fairly powerful computer with lots of room for further expansion. Excellent screen. The Windows 8 is lousy but you have little choice here. The computer comes with many useless programs and a Norton trial that doesn't work because they don't supply a activation key.
OK so full disclosure I put Ubuntu on this computer immediately after buying.But a few things with this computer that I noticed, that shouldn't be happening considering it's pretty high-end.1.) The wifi tends to cut in and out, especially when using Ubuntu.2.) Both USB outlets on the left side stopped working?! Same for Ubuntu and Windows. I've had this computer for all of three months.3.) The touchpad is pretty terrible. It's oversensitive I think?
So I bought a USB mouse. Which is using one of my two currently working USB outlets. (I'm really kind of bitter about it. )Anyway, it's an OK computer but if I would have known about its weird quirks I probably would have went for another model, and I don't think I will buy from Toshiba again unless something significant changes. (PS Windows 8 alert: Windows 8 really stinks. My computer is not a tablet?? What are they even thinking.
These are the 15" touchscreen, non-touch and Ultrabook models that are currently being sold with Ivy-Bridge and Haswell processors at Best Buy. This system has an HD1080P panel and the resolution looks great compared to many of the poorer 1366*768 screens. The screen is also very bright and vibrant; I'm assuming it to be at least 300+ nits compared to the other models at around 200 nits or less.
The following categories are my impressions of different areas of this system.Display:This system has the best display of any Toshiba laptop I have seen to date; many other laptops too. If it weren't for the slightly off viewing angles, I'd have guessed it to be an IPS display. When comparing this screen to the other Toshiba models on the display floor at Best Buy, it looked vibrant and bright in contrast to the murky and dim screens of the other P55 series Toshibas.
while it's nothing incredibly special, it does look nice and professional.SummaryIf you found my review helpful, please give it a "thumbs up. "I would recommend this system to anyone looking for a well-rounded, up-gradable and powerful desktop replacement that is occasionally on the go with it. Overall, I'm impressed with the build of this system.
require this in the future. The Lenovo Z10 is not.Performance: Some features of Photoshop such as applying filters which used to make me want to kill myself while I wait for them to render on my old computer (with 4gb of RAM), works fast enough that I am happy with it. I have not tested this on Lightroom, which is more RAM intensive, but I am sure it will be fine.
i do not recomend this computer. i bought it about a month ago, and let me tell you. its not as fast as should be,  and i'am not talking about internet, i am talking about performing regular tasks  like opening a file, or a program. its just slow! i guess it has alot of bloatware running in the background, alot of crap nobody needs nor wants. I'm not buying toshiba ever again.and by the way windows 8 is still horrible
