I still have a laptop (XP) with those specs that I actively test and I can confirm that Extjs 4.x loads super fast.

Hopefully could try the EXTJS 5.x in near future. Thank you

It became very clear in SenchaCon 2013 that Sencha will still support and optimize code for IE7,for me is a misktake drived by the developers survey.
I really doubt that the 70% who said that ie7 support was mandatory really balance what they are gaining and what they are losting.
It is like sayingo you want Ice cream ,I mean one ball of chocolate, one ball of vanilla and another ball of Cherry.
90% would say, Of course I would like three balls of Ice Cream.
OH HEY,I forgot to say that Chocolate and vanilla ones will cost you one dollar each, but the cherry one will cost you U$ 2500 dolars.
Maybe 5% percent,those who really love cherry would pay for this luxury.
Keeping IE7 probably will increase the price of EXTJS5,delay every release of the plataform, decrease the performance and make things more error prone due to the fact that you really have to write much more complicated code to deal with an illogic browser.
Even for those who still have XP there are a myriad of other free browsers that could be used and of course IE8,I Can be completely wrong, just my 1,50 cents.

There has been a fair bit of discussion around the need for legacy browser support.
Generally there is a large chunk of users of Sencha that require it - mainly in the corporate sector that tend to be slowto move with the times and reluctant to install anything that isn't Microsoft supported.
I used to work for a Bank and this was the case - was like pulling teeth to get then to move from IE6 to IE8.
I would like to see the framework fork at some point - or if Sencha manage to partition the framework well enough into packages have a legacy option that can be turned off.

For me the logical way to fork it is to keep supporting 4.x in maintenance mode for legacy IE and to burn some browser compatibility bridges in ExtJS 5. It's not exactly sensible to be using bleeding edge dev tools on legacy environments anyway.

IE8 is going to become the new IE6 though. I still know of companies migrating to IE8, so by the time they migrate away from it we could very well be another 5 years down the line. And the thing is that IE8 at this point has poor enough implementations of newer standards from the HTML5 sphere that it does affect the basic design of the code you're writing.
In SenchaCon 2013 highlights that I read it was stated ver clear that IW IE 6 and IE7 area Dead but they wull still support IE8.

I couldn't agree more. As long as ExtJs 4.x is long term supported, maintaining support for ancient browsers is a huge waste of developer resources when creating an entirely new version of the framework. Dropping support for anything older than IE9 in ExtJS5 will be a huge leap forward.
