( CNN ) -- Apple 's Steve Jobs gave quite a monologue Monday , dressing down competing makers of smartphones , tablets and software . The brunt of that was aimed at Google , which makes the Android software that powers smartphones from a range of manufacturers including Motorola , Samsung Electronics and HTC . First , Jobs expressed skepticism about how Google reports its number of Android users . This is an issue Jobs has raised in prior speeches , yet he freely addressed the point of comparison , saying Apple has activated 75,000 more iOS devices over the last 30 days compared to Google 's last reported Android activation number . Jobs , who made his comments in an unusual appearance on Apple 's quarterly earnings call with investors , then took issue with the geeky argument of open versus closed , which refers to how transparent a system 's source code is to developers . `` Google loves to characterize Android as open , and iOS and iPhone as closed , '' Jobs said . `` We find this a bit disingenuous and clouding the differences between our two approaches . '' He called Android `` fragmented . '' He highlighted how Android handset makers install layers on top of Google 's software , which can introduce unexpected problems . And Amazon , Verizon Wireless and Vodafone say they intend to create their own digital stores to sell applications to Android users , despite Google 's own Marketplace . `` This is going to be a mess for both users and developers , '' Jobs said . `` We believe integrated will trump fragmented every time . '' Later , Jobs criticized Google for not having a version of Android that plays nicely with tablets . The animated executive then turned his attention to tablet-device makers , which are ramping up production in advance of the holiday season . `` Almost all of them use 7-inch screens , as opposed to the iPad 's 10-inch screen , '' Jobs said . `` This size is n't sufficient to create great tablet apps . '' Jobs joked that people would need to sandpaper their fingers in order to use these gadgets comfortably . While a smaller tablet is obviously more portable , he says consumers wo n't want something that replaces a smartphone . `` Every tablet user is also a smartphone user , '' he proclaimed . His comments will perhaps put an end to speculation that Apple will make a 7-inch iPad . `` We think the 10-inch screen size is the minimum screen size required to make great tablet apps , '' he added . Additionally , Jobs said tablet makers will have a hard time matching Apple 's prices . The most inexpensive iPad sells for $ 499 . Competitors ' tablets will be `` dead on arrival , '' Jobs said . He added : `` Sounds like lots of fun ahead . '' Jobs began his comments Monday by relishing in Apple 's successes with the iPhone 4 , pointing to the 14.1 million smartphones the company sold during the recent three-month fiscal period . That tops Research in Motion 's 12.1 million units sold , as Jobs was quick to note . `` We have now passed RIM , and I do n't see them catching up to us in the foreseeable future , '' Jobs said . `` I think it 's going to be a challenge for them to create a competitive platform and to convince developers to create apps for yet a third software platform , after iOS and Android . '' RIM , the Canadian smartphone manufacturer , is popular with corporate IT departments for its tight security mechanisms and reliable keyboards for tapping out long emails . Despite the slow quarter for RIM , the BlackBerry maker still has the highest market share of smartphone users , according to independent data . The company is preparing to enter the tablet market with its PlayBook , an area dominated by Apple 's iPad . `` RIM has a high mountain to climb , '' Jobs concluded . On Adobe Systems , which makes the Flash platform that powers most of the Web 's video , Jobs dodged questions . He finally addressed the lack of Flash support on the iPad , iPhone and iPod Touch , saying : `` Flash has n't presented any problem at all . '' On Nokia , which sells the most cell phones worldwide , Jobs said : `` Nokia is the biggest , and we admire them for being able to ship the number of handsets that they do . But we do n't aspire to be like them . '' `` Nokia makes $ 50 handsets , and we do n't know how to make a great smartphone for $ 50 , '' Jobs said . `` We 're not smart enough to figure that one out yet . '' For the famed business leader to take part in the company 's earnings call is strange enough , as he acknowledged after being introduced in the meeting Monday . ( Apple broke a number of its sales records this quarter . ) But his comments were even more unexpected . Oftentimes , his discussions would come back to Google , as they did again after a question about Nokia . `` Android is our biggest competitor , '' Jobs said . `` They outshipped us in the June quarter when we were transitioning to the iPhone 4 . '' `` Eventually it will turn into a zero-sum game or a lot closer to that , '' Jobs said of the smartphone market . `` Right now , iPhone and Android are winning that battle . ''
Apple 's Android participated in the company 's earnings call , which is unusual . Google had choice words for competitors including Adobe , Jobs , Nokia and Adobe . Apple is Apple 's biggest competitors in the smartphone industry , Jobs said .
