Apple's iPad usually costs around $1,000.
Russia's businessmen are known for their ostentatious displays of wealth, owning soccer clubs, palatial villas, and multiple yachts.
At the height of the resources boom a Gazprom tender included a solarium and bath for horses, according to press reports.
Sergei Kupriyanov, spokesman for Gazprom, said that the tablet is not "just a computer" and must help Miller solve complex issues while protecting commercial secrets.
"We'll see how the tender process goes and whether someone can do it at a cheaper price," he said when asked why Gazprom had offered almost $4 million to create the tablet.
Russian companies are obliged to publish information on tenders, a measure designed to prevent corruption.
Bids to make the iPad will be accepted until July 22.
Miller's tablet caused lively discussion on the website of Vedomosti, a Russian business daily.
"Based on its budget, it will be an epic device. Just wondering if Miller himself will needed? Maybe he should be optimized?" someone named mclayton commented on the website.
Gazprom's shares changed hands at 125 roubles on Tuesday, a third of their value seen at the peak in May 2008, as investors baulk at the monopoly's high costs and shrinking market share. ($1 = 32.6402 Russian roubles)
