I thought answering to old threads is awkward and if you think its not I will.

I have another system with me to watch movies or to do extensive tasks. The present laptop I am using only to learn programming and so I think I need extra battery backup and faster response and wifi.

I thought Redhat is best because it provide only the basic tools for programming and give less importance to others like multimedia etc.,

The present opensuse iso image is corrupted I think so what many unwanted errors appearing. After two months I am planning to use opensuse 13.2 of course.

Seriously??? Answering questions that YOU have been asked, isn't 'awkward'....it's polite.
Programming doesn't need 'faster response' or wifi...it needs a CPU and RAM, and even THAT doesn't matter. Compilers work the same on fast machines or slow..if you have code bugs, they're there no matter WHAT machine they're on. And having a laptop for movies or 'extensive tasks' and one for programming is pointless and absurd.
Wrong...ANY distro of Linux has the same tools available for programming. And AGAIN, unless you're PAYING FOR IT (and NOT a free 30 day evaluation), you shouldn't use it. This is another good example of you ignoring advice, and doing NO research on your own.

AGAIN, there are HUNDREDS of threads on this very site that you can easily find about RHEL vs. other distros.
AND THIS IS WHY YOU WERE TOLD QUITE SOME TIME AGO; REDOWNLOAD THE CORRECT IMAGE AND REINSTALL IT!!!!!!...you were told that VERY plainly, and you said it was 'tedious' to do it.

AGAIN...you ignore advice, and don't seem to understand what people are telling you, and you're doing what you want...so why bother posting questions??? Go get whatever laptop you want, load whatever you want, and good luck. You've been here for years now under several different names, but don't seem to follow things.
