Web browsing from across the room tends to be a bad experience.
You can get more apps, better apps and better support with an ordinary HDTV, but you add a small "Media Server" box and hook it up with HDMI cables. I like the Western Digital TV Live box ($99). It gets frequent updates, plays almost all my video files, gives me 28 streaming apps, etc.
My "smart" bluray player gives me 8 apps and gets updated about once per year.
The small media servers exist for apps so they tend to be more aggressive about adding features and updates.
Roku, AppleTV, etc. are all other examples of media servers.
The apps usually include: Netflix, HuluPlus, Pandora, YouTube, CinemaNow, BlockBuster - all streaming services. Most are for subscription but some are free.
My advice is you get a MediaBridge brand HDMI cable from Amazon ($9-$20), and a WD Live box ($99). Then get the non-smart version of the LG television.
Chances are it will work better and cost less than the $300 bump for the smart model.
Hope this helps.
