Heya, This raises a good question as to what FLEX is really meant to do. In that, you've stated that you've experienced memory leaks and so forth, and i must admit if i load too much into the one screen stack, i too will see some CPU climb - but thats easily fixed by removing un-needed containers/controls (ie its no use having a mini virtual OS within a browser) along with varies data/memory management techniques applied (de-reference variables when finished, page breaking data etc).
FLASH Player by its very nature has a limited amount of memory budget to play with and if you want to store 80,000 rows of data inside a DataGrid then yeah memory will hike. In reality though most folk will only use the top 100 at the very most on any search criteria - unless they are doing some crazy MS Excel type situation. Anyway the point i'm trying to make is that if the price does increase, and peoples expectations of what FLEX should DO vs what its capable of DOING (ie even if you compared FLEX App against a .NET Windows Form / JAVA SWING style app in terms of performance, you have to agree that FLEX will look poor (performance wise) on that regard. Yet in development costs and accessing it via the web, it kind of doesn't seem that bad - especially in file sizes. This is where I personally found it a point of contentation in that, as soon as i mentioned its capabilities of emulating thickware clients via browser, straightaway people i've pitched it to in the past have gone on the comparisons route - neglecting the keyword being, emulation. To me, FLEX is like buying VW BUG (Car), and stripping its panels/visuals away and putting porsche replacements in its place.. it looks and in many ways can sound like a porsche, but its no porsche its a VW made to look like one. (I recently saw a car do this very thing and you'd swear you were looking at a porsche..until it was started). Analogy was probably weak.... Price wise, maybe Michael is right, maybe that for $15k per CPU it HAS to go toe to toe with a thickware client aswell as maintain a smaller payload in terms of bandwidth consumption.
