Toshiba Portege R835: Less Ultra, More Notebook

System Performance
Essentially what we're dealing with when we look at the Toshiba Portege R835's full voltage mobile processor is just how much performance an ultrabook sacrifices to hit that 17W TDP on the CPU. There's more to it than that, but there are also potentially some interesting wrinkles going on with the Intel Core i5-2450M in the R835 that may manifest themselves.
The PCMarks are always going to skew wildly towards any system that enjoys an SSD, so the bottom shelf 5400RPM hard drive in the Portege R835 isn't doing it any favors here. Let's see what happens when we shift performance squarely to the CPU.
The i5-2450M pulls off an impressive run, demonstrating that there's still a notable difference between a low voltage and a standard voltage chip. The R700's last-generation processor is soundly beaten by this generation's low voltage chips, the turbo-less i3-2367M excluded.
Without DirectX 11 support, Sandy Bridge graphics can't run 3DMark11, but 3DMarks Vantage and 06 demonstrate the importance of both having a faster processor and a faster IGP core. You're not going to be running wild in Battlefield 3 on the Portege R835, but nerds like me can still enjoy games like Magic: the Gathering - Duels of the Planeswalkers 2012 on the IGP.

I have a Toshiba R705. Basically the same laptop, right down to the cooling system design. When running heavy-duty processes (30min of straight number crunching) my CPU core temperatures usually stay in the mid-70s. That's more than 25C below the recommended thermal limit for my processor (105C).I can't imagine any normal usage case, even heavy duty usage, where I would ever get near 105C. I'm guessing the cooling design is okay for all 'normal' usage scenarios, even heavy-duty usage.
That being said, I think that putting all of the intake vents on the bottom of the system is a really dumb idea. If you stream movies with the bottom of the laptop on a bed or sofa - look out! It's going to get toasty in there...

please keep talking about lcd quality, I bought my sager np8130 (p151hm1) when you guys spoke about the LCD, it was fairly good and it was great performance for the price and dual link dvi for my 120hz displayhexanerax - Saturday, March 31, 2012 - link
How difficult is it to write a PPI agnostic app? ( to those not in the know,all elements of the UI should appear exactly the same physical size on all monitor resolutions meaning a high ppi display UI looks awesome and this low res junk that manufacturers are hawking will end).Hi res support has to be coded into the os and done right. I have enough problems with un-clickable buttons and unreadable text due to poor dpi scaling in some poorly written apps. Getting correct PPI information from the panel and scaling display elements to actual physical dimensions would be great, allowing users to really see the difference and cough up the extra dough if inclined.
Writing this on a great 1900 x 1200 17" LCD on my Dell Precision M6300 ( never upgraded due to the 16:9 fetish in most product lines.

$ for $ , an SSD will translate to better user experience than a higher clocked processor for most normal usage scenarios. For those looking for a fast, low priced system, adding a 40 GB SSD and going for a lower clocked cpu or lesser cores will be a better option than a 500 GB 5400 RPM HDD with a high frequency processor. Enthusiast or not an SSD is no longer an option. I can understand using a Mechanical drive for critical data considering the issues that SSDs have had in the past but if you are buying a budget laptop, how critical is the data you are storing? Think cloud storage + SSD for the best experience. Buy an external HDD.On a system with a Corsair Force F120.

I don't need more than two USB ports (to be honest I can get by with one).I don't need a Firewire port.
I don't really need a HDMI or D-Sub port either.
I can go without Bluetooth.
That should be nearly enough to get a decent screen instead.
Yeah so one or two USB ports, a gigabit ethernet port and the power port are all I need.

Judging from the last picture on the 2nd page, the body appears to be magnesium alloy, not plastic. Mag alloy feels a lot like plastic (especially when painted) since its thermal conductivity is extremely poor and thus doesn't feel cold to the touch (unlike say, aluminum found on Apple's devices)hexanerax - Sunday, April 1, 2012 - link
Just for the record :-http://www.jsw.co.jp/en/mg_f/mg_mg_f/mg_mg_chare.h...
It probably feels less cold because it is conducting heat from the system outwards.
The paint probably has more to do with this feeling than the thermal conductivity of the metal. Aluminum is generally left unpainted ( polished, brushed ) or anodize in color which leaves the thermal properties unchanged.

The last time many consumers have seen a monitor with decent image quality was when they were using a CRT.If more consumers could see a side by side of your average TN panel and some of the amazing IPS and PVA panels out there a lot more people would seek out the better monitors. Right now people just don't know any better.
I use two monitors at home, the Dell 3007wfp-HC and a Yamakasi Catleap Q270 (27" S-IPS, same panel as the Apple Cinema display). Both are S-IPS panels, both are very high resolution, and both are amazing. To go back to some lower resolution TN panel now would make me want to claw out my eyes.
Luckily my HP laptop has a very good TN panel in it that even has good viewing angles. One thing that will have to improve a little bit for the high resolution displays to be a good fit for everyone will be better font scaling. Windows 7 has fairly decent support for it and modern browsers also allow some control but it still needs to be improved.

For better or worse, ultrabooks are coming down in price, and are still using crappy panels.Except for Delta E, and compared to the high-end Sony, it seems like the MacBook Air line from last year still beats most of the panels in these new Ultrabooks:
