TV 40-46" 1080p 120hz with FULL internet browsing capacity

Question

It looks like there are only 2 tv makers that allow for the full internet access (LG and Sony).  I can't find a reasonably-priced sony KDL-40/46EX620 (sold out by BBuy).  KDL-40/46EX720, the next model seem to be at 60 refresh rate.  
How does the blu-ray work?  can it allow the FULL access to the internet or is it only for connection to the pre-set locations, such as u-tube, netflix etc?  
Another Q:  Do I need the smart TV to watch my downloaded movies?
tnx

Let me just add some comments here that conflict with some info already provided.  First of all, Sony has not reverted to cheap parts to build their TVs, and they are not as bad as suggested.  However, I do agree that Samsung and LG LEDs have better quality, as do Panasonic plasmas (not their LCDs), and of course Pioneer hasn't made a TV in many years.
The reference to the problems with 120 hz was to a four year old post that was indicating problems with 24 fps film based material.  Many of these problems have been alleviated in the past few years, however many people (me included) would turn this function off (which is always an option) when watching 24 fps material (such as Blu-Ray).  On the other hand 120 hz does do a very good job of reducing blur and providing a sharper image for tape based material, especially beneficial for all sporting events.  It is worth the extra cost.
The reference to full web browsing by some manufacturers is probably somewhat of an overstatement, however those with a built in browser can link to well over 95% of the sites that google would bring up.  The most exceptions are major video providers such as ABC-TV, CBS-TV, etc.  The built in browser is still a plus for these TVs, but they won't totally replace your computer.
The TVs with the browser are the higher ends of LG and Samsung (models 8000, 7000, and I think the 6900).  The nice thing about the Samsung models is that they include a full QWERTY keyboard on the flip side of the remote.  The Sony Google TV also has this capability, but I believe that it is overpriced and not as good quality of picture as the LG and Samsung models.

Perhaps you can provide us with some verification of your poitns?  Particularly about the 120Hz.  For your information, 24p interpolation is the only time if might actually do some good!  So, you have it backwards. If you can provide any verification, other than from the manufacturers, that shows that it has any affect on motion blur, then post away.  Hint: Flashing the same image over and over does not make it sharper, and if motion interpolation is involved, the frames created in between the 60Hz broadcast frames are artificial, and cannot be sharper than the original.  SO, post away...I'll be interested...
I guess you also have not used the browers that you reference that you claim can access 95% of websites that google brings up.  Startling numbers that go against both my real world experience and any testing/review/rating that I have ever known.
As far as to the quality of Sony TV's you are entitled to your opinion, but with the high return rates, the high failure rates, and the legendarily bad Sony "customer Support", anyone who knows anything will recommend against them.  They *are* cheaply made.  They *DO* use inferior parts.  There sets *ARE NOT* competitive in picture quality to the other big name players.  Even a cursory, casual comparison will veryify this. 
A full QWERTY keyboard is nice, but that does nto equate to a full browser.  The operative word is full....not borowser.
