Pros: Overall good value for the price

Cons: No USB 3.0, but I guess you could put in an expansion card.

Overall Review: Read the specs: this is a "Student/Home Office" machine, not intended to be a workstation for a corporate network or domain. If you're looking for that, then upgrade to Win8 Pro, or buy a machine that comes with it.

Pros: A barely adequate telescope for a budding astronomer

Cons: Poorly made mount, over-blown magnification ability, poor quality eye pieces.

Overall Review: This is a classic 60mm refractory telescope; that is, the larger lens at the front of the telescope is 60 millimeters, or about 2.4", in diameter. The diameter of this lens, in accordance with certain optical physics laws, determines the limits of its performance. For one thing, the maximum usable magnification for any telescope this size is about 100X. Any more would be like using a powerful magnifier on a newspaper photograph: beyond a certain magnification, you don't really see any more detail. This being said, a telescope like this can show you such things as the mountains on the moon, color bands and the satellites of Jupiter, the rings of Saturn, and some of the brighter of the "deep-sky" objects (the Orion Nebula, the Andromeda galaxy, and such.) As long as its limitations are recognized, it can be an economical way to spark a youngster's interest in astronomy.

Pros: Solid drive, runs reasonably cool, and relatively fast data transfer with USB 3. However, if you are running any Win7 or earlier (newer versions of Win7 64-bit may not have this problem), you may have some difficulties in using all the capacity of this drive. If you have WinXP, or 32-bit Win7, you definitely won't be able to access all 4TB. This is not a problem with the drive: it's a limit built in to older versions of Windows because at the time they were written, drives this large were simply undreamed of. There is a workaround, though. Go to (support<dot>microsoft<dot>com<forwardslash>kb<forwardslash2581408) (I had to do it that way so NE would accept it!). It tells you how to configure your version of Windows for HDs larger than 2TB.

Cons: Manufacturers need to let consumers know of this difficulty in their literature. A utility to "adjust" the OS configuration would be nice!

Pros: Stable, easy install, 64-bit supports lots of RAM, good software and hardware compatibility,

Cons: Can't buy the "retail" version that lets you install on 3 machines anymore. This makes it expensive if you're wanting to install it on more than one machine. Also, who is the guy at Microsoft with the microscopic vision? Jeez, guy, at least supply a cheap plastic magnifier for the rest of us!

Overall Review: My company had been using WinXP for several years, and it was fine. However, when Microsoft quit supporting it, the "upgraded" all the company machines to Win8. Oh, my! Nothing but problems. Software incompatibility, hardware (printers, mostly) incompatibility, and many other difficulties. Somehow, they managed to swing some sort of deal and "downgraded" to Win7 Pro 64-bit. All the problems miraculously went away! If you're planning on upgrading an older computer, stick with Win7 - as long as it meets the minimum hardware requirements. Win 8 just has too many potential problems for me to be able to recommend it.

Pros: Absolutely none.

Cons: Slows computer down: requires credit card up front: customer service unresponsive: misses malware

Overall Review: This should be listed in the Webster's Unabridged Dictionary as an example of "junkware." I installed this trash program about two months ago on my laptop (i7 with 8gb RAM, 750gb HD, Win7 Pro 64 bit), and it bogged the machine down drastically. Before installation, boot up took about 45 seconds: after installation, about 3-1/2 minutes! An Excel spreadsheet that used to take about 12 seconds to recalculate now takes nearly 1-1/2 minutes! It even slowed downloads and uploads by nearly 100%! If you try to install new software with this stuff operating, you'd better be ready to go get lunch, because it takes forever! I first emailed, then tried to call tech support at iYogi (they are the publishers), and never was able to get any kind of response from them. After struggling with this software for over a month, I finally gave up and uninstalled it. Unfortunately, the normal uninstall procedure doesn't do a complete job: there are numerous registry entries left behind, and it will not allow you to enable install or enable any other anti-malware or anti-virus software, including firewalls! It took me nearly another month of digging and cursing to remove all traces of this trash. I finally have my computer back to proper operating specs, and it's running a good, reliable and trustworthy Internet Security software package. Please, believe me - you do NOT want to install this software! You might as well purposely install the "Loveletter" over-writing virus or the "Pgpcoder" ransomeware malware.

Pros: Good display, decent battery life, wifi works very well. The Core 2 Duo is an excellent CPU, and if you boost the RAM to at least 4 gigs, this thing will scream on all but the heaviest-duty applications. It is NOT a gaming machine, and should not be viewed - or reviewed! - as such.

Cons: USB port placement could be better - they get in the way sometimes.

Overall Review: Remember - this is a 32-bit WinXP machine. You can't upgrade WinXP to Win7 - you have to do a complete wipe and install. That's okay, though, I put Win7 64-bit on mine, it got rid of the "bloatware", and it works beautifully.
